Welcome!

Welcome to ScreenPower for Windows!  TeleSensory's exciting new
addition to the ScreenPower family of products allows individuals who are
visually impaired to effectively use the Windows operating system.

The goals for ScreenPower for Windows far exceed the ability to just read
the screen.  SPWIN goes a step further:  The information about the
contents of the screen are arranged in such a way as to allow the blind
user to achieve a very fast overview of the total screen layout as well as
the details.  The ability of SPWIN to combine elements which functionally
belong together and represent them as one plays an important role in
achieving this result.  In addition, an elegant system of orientation help
and search functions allow you to work through even the most
complicated screens.

ScreenPower for Windows provides high-quality speech and braille
access to all elements on a Windows screen.  The software can be used
with a wide variety of speech synthesizers and braille displays.  During
installation, the user can choose to use speech output, braille display, or
an integrated combination of both options.  

A unique set of screen exploration commands allows the user to identify
and use each window, icon, button, and other item on the screen.  All
navigation functions are assigned to the keys of the number pad or braille
display panel keys.  This provides a clear distinction between
ScreenPower operations and Windows keyboard commands, and
significantly reduces the risk of key conflicts.

ScreenPower for Windows can be easily customized to suit the user's
needs and preferences.  Customization options can apply to a single
window or alter a global function.

Although the visual nature of the Windows environment will always
present some challenges for the visually impaired computer user,
ScreenPower for Windows offers a sophisticated, flexible, yet easy-to-use
functional interface.  


          
Manual Organization
          
          This documentation is divided into five parts:
          
          Part One:  Definitions and Concepts This section is intended to help
          the user get acquainted with important definitions and concepts in both
          Windows and ScreenPower.  The advantages and inherent problems of
          the Windows operating system are discussed, and important Windows
          elements are defined.  The ScreenPower interface is then explained.  The
          user is introduced to the concepts of focus tracking and screen navigation. 
          Keypad overlays, mouse control, and other functions are also discussed.
          
          Part Two:  Installation Guide This section describes the procedures for
          installing ScreenPower for Windows.  Several configuration alternatives
          are explained.  A troubleshooting chapter is included to help you resolve
          unexpected problems.
          
          Part Three:  Tutorial The tutorial section will help you become
          acquainted with ScreenPower commands and concepts through hands-on
          experience.  Step-by-step instructions guide the user through some basic
          Windows operations.  The Exploration functions are used to explore a
          Windows screen and several ScreenPower utilities are introduced.
          
          Part Four:  Reference Manual The reference manual provides detailed
          information about all functions in the ScreenPower for Windows software. 
          Use this section to gain a comprehensive understanding of each
          command and utility.  A chapter describing available customization
          options will help you learn to adapt ScreenPower's performance for new
          Windows applications.
          
          Part Five:  The Appendices These appendices are intended to serve
          as a quick reference guide to Windows and ScreenPower functions.  
          
               Appendix A lists the functions available in each keypad
                         layer.

               Appendix C is a list of the keyboard commands defined in
                         the  Windows operating system.  
          
               Appendix D is an alphabetical list of some important terms
                         used in this manual and their corresponding definitions.
          
               Appendix E explains the abbreviations used to represent
                         Windows objects in the ScreenPower navigation tree.
          
               Appendix F provides information about using different braille
                         displays with the ScreenPower for Windows software.

How To Use This Documentation
          
          Although it is not necessary to read this entire manual, we recommend
          that you thoroughly review the first three parts.  Part One will provide
          some important information about Windows, then explain how
          ScreenPower can help you interpret and use Windows's complex and
          highly visual screens.  Part Two will help you correctly install your
          software.  Finally, the tutorial section will walk you through some typical
          Windows operations and help you become familiar with some of
          ScreenPower's innovative features.
          
          Part Four, The Reference Manual, should be used to increase your
          knowledge of ScreenPower functions and customize your access once
          you actually begin to work with Windows.  A thorough understanding of
          Windows concepts and the Windows applications you plan to use will help
          you more effectively use this section.  Although some Windows elements
          are defined in this documentation and some basic Windows operations
          are explained, we recommend that you also read your Windows Operating
          Guide and the documentation for your specific applications.  Then use
          Part Four of this manual to fine tune your ScreenPower skills and working
          environment.
          
          
Typographical Conventions
          
          The ScreenPower documentation uses some simple typographical
          conventions.
          
          Key names are written as they appear on a standard keyboard.  For
          example, the Escape key is referred to as Esc.  
          
          Text or alphanumeric keys to be pressed will be written within quotes.  Do
          not type the quotes unless told specifically to do so.  Although we write all
          commands in upper case letters, they do not need to be typed that way.  
          
          File names are always shown in upper case (i.e., FILENAME.TXT), but
          you can type them in lower case.  
          
          When two keys should be pressed simultaneously, the keys are shown
          separated by a hyphen.  For example, Ctrl-N means press the Control
          key, hold it down, press the "N" key, then release both keys
          simultaneously.  When the keys are to be pressed one after the other,
          they are listed without spaces.  For example, 004 means to press the zero
          key twice, then press the four key on the keypad.  Keypad presses the
          end in a key other than a number are shown with a comma before the last
          key.  For example, 08, Plus means press the 0 key, then the 8 key, then
          the Plus key.
          
                    Part One:  Definitions and Concepts
          

Overview

This section will introduce you to many terms and concepts used by both
the Windows operating system and the ScreenPower for Windows
program.  Whether you are already familiar with Windows or taking your
first tentative steps towards learning this new way of working with a
computer, you should read the following information very carefully.  A
thorough understanding of Windows elements and knowledge of the
concepts behind the ScreenPower interface will help you to more quickly
begin using the many powerful applications available for Windows.

Although this manual is not intended to be a Windows tutorial, this section
will describe many common Windows objects and their functions.  This
information should be used as only a starting point for your study of the
Windows operating system and the ScreenPower program.  It is very
important that you learn about the specific applications you intend to use
in Windows.  If you have a clear understanding of the tasks you intend to
perform and know which application functions will allow you to accomplish
your goals, you will find it much easier to begin exploring the Windows
environment with ScreenPower.  


Essential Information About Microsoft Windows

In the past few years, "Windows" has become an all too familiar word to
computer users.  Although some controversy continues concerning the
relative merits of Windows as compared to other operating systems, most
people seem to agree that Window's user interface is especially easy to
learn and use.  For this reason, many businesses and schools have
switched from DOS to Windows, and this trend has inspired the
development of many powerful new Windows-based application
programs.  Yet, many visually impaired computer users still growl the word
"Windows" in irritation or even whisper this word in dread.  

Despite the sophistication of modern access software, the graphical
Windows screens remain baffling or even inaccessible to many braille and
speech output users.  While the graphics and text on a Windows screen
can provide a great deal of information visually, it can be difficult to
convey this information in a meaningful way using traditional output
strategies.  Since pictures and text can be any size and can be placed
anywhere on a Windows screen, reading information in the typical linear
          (row, column) fashion frequently fails to provide useful information. 
          However, limiting information output to only those screen elements which
          "appear" to be most important could seriously mislead a visually impaired
          Windows user or prevent effective use of an application's options.
          
          The ScreenPower for Windows software attempts to solve these and
          many other problems by providing two different operating modes.  The
          first mode provides information only about those items on the screen
          which are intended to catch the attention of the sighted user.  The second
          mode allows the user to explore all items on the screen using a unique
          organizational strategy.  Both of these modes (which will be described
          later in this section) require the user to have some understanding of
          Windows concepts and a working knowledge of several screen elements.
          
          The following paragraphs and the Opening Windows tutorial tapes
          included with ScreenPower for Windows will define many important
          aspects of Windows.  If you would like more information about any of
          these topics, please refer to your Windows documentation.
          
What Is Windows?
          
          Like DOS, the Windows operating system is a platform for file
          management and application launching.  That is, Windows helps the user
          to organize information and programs on disks, to control the flow of
          information to printers and other peripheral devices, and provides a
          framework for using application software.  However, Windows offers
          several features which are not integral components of the DOS operating
          system.  For example, Windows has built-in task switching and
          multi-tasking functions.
          
          The task switching function allows a user to run two or more applications
          at the same time.  By issuing a single command, you can then instantly
          jump from one application to the other.  Thus, you could retrieve a report
          in WordPerfect, load a Lotus spreadsheet, then quickly move between the
          two files as necessary.  If you find you need even more information, you
          could then access a database file or even retrieve a second spreadsheet. 
          Clearly, this feature can help you to use your application programs very
          efficiently.
          
          Multi-tasking is simply task switching taken one step further.  In task
          switching, you move from one application to another when necessary. 
          When you leave an application, you assume that all activity stops and the
          program waits for you to return.  When you take advantage of the
          multi-tasking feature, you initiate an action which will continue for some
          time, then switch to another application where you can continue to work
          rather than waiting for the first task to be completed.  For example, you
          could run a telecommunication program and begin downloading a file from
          a bulletin board, then switch into your word processor and continue to
          write a letter.  The activity in one application has no effect on any other,
          and you never have to stop working while waiting for a long sorting or print
          job.  This feature can significantly improve work efficiency and productivity
          in some situations.
          
          The number of applications you can run concurrently is limited only by the
          amount of memory in your computer.  However, Windows's powerful
          memory management strategies will help you to take full advantage of
          these features.
          
          Another significant advantage of the Windows operating system is its
          consistent user interface.  Most Windows-based applications use the
          same objects and menu structures defined in the program manager.  This
          makes it much easier to learn and begin using a new application.  
          
          For more information about these features and other operating system
          enhancements, consult your Windows documentation.  
          
Differences Between Windows and DOS
          
          Once you understand the primary purpose of the Windows operating
          system, you can begin to explore the many functional differences between
          this package and the familiar command-driven DOS environment.   These
          differences account for much of Windows's popularity among sighted
          users and present some problems for both users and developers of
          Windows access software.  The following paragraphs will discuss some of
          these functional differences and begin to explain how ScreenPower can
          be used to solve these problems.
          
          The GUI Interface
          
          Perhaps the most obvious difference between DOS and Windows is the
          user interface.  The "user interface" refers to the overall appearance of an
          application's screens and the methods used to allow interaction between
          the user and the application.  
          
          In DOS, the typical computer screen is capable of displaying up to 25
          lines of text with a maximum of 80 characters on each line.  The user
          looks for a cursor next to a prompt such as "C:\>" and enters commands
          at this location.  Information moves onto and off of the screen in a
          predictable manner, and screen formats are generally the same each time
          a utility or application is executed.
          
          Windows uses a much different user interface.  The concept of neat rows
          and columns of ASCII characters is completely abandoned, and
          information can be placed anywhere on the screen.  The Windows screen
          is comprised of small dots of light called "pixels."  The screen can have
          640 columns and 480 rows or 1,024 columns and 768 rows of these pixels
          depending on the resolution capability of your screen.  Characters and
          graphics are drawn on the screen by lighting and dimming these pixels in
          the appropriate patterns.  Thus, information may be written in any font. 
          Since the term "font" refers to both the style and size of characters,
          important information can be conveyed simply by altering one of these
          character attributes.  To further complicate matters, Windows screens
          may also include graphics.  Lines are frequently drawn to separate
          information into logical sections, and small pictures or symbols are used
          to represent functions or applications.  
          
          This graphical user interface (GUI) presents many challenges for a
          visually impaired computer user.  First, a way to identify the graphic
          symbols had to be devised.  Second, a means of organizing and
          presenting the information on the screen in a meaningful way had to be
          developed.  Finally, a way to identify and display important text attributes
          had to be found.  ScreenPower for Windows has solved each of these
          problems and presents this information in a logical manner which allows
          many user options.
          
          Cursor vs. Focus Tracking
          
          Another important difference between DOS and Windows is the method
          used to indicate the focus of current activity or interaction.  In DOS, users
          are accustomed to relying on a "cursor" to provide this information.  The
          cursor is either a blinking bar which indicates where the next character
          entered will be displayed or a screen highlight which indicates the
          currently selected option.  In either case, a speech or braille access
          program can provide specific information about current program activity by
          announcing or displaying the text at the cursor.  Also, since all DOS-based
          applications display ASCII characters in a strict 25 line by 80 column
          matrix, additional information can sometimes be obtained by identifying
          the cursor's location on the screen.
          
          Windows does not use a cursor in the same manner.  Instead, a variety of
          visual devices are used to indicate on which screen element the user
          should "focus" his attention.  Sometimes, the focal point can be identified
          by an unusual screen highlight.  At other times, dotted lines or other
          graphic symbols are used to surround or point to the selected item.  In
          either case, ScreenPower for Windows tries to detect the point of focus
          and provide information about this item.  This technique is called "focus
          tracking" and is one of the two operating modes which are always
          available to the ScreenPower user.
          
          The Mouse Pointer
          
          A mouse is a small device which can be connected to a computer and
          used to move a "mouse pointer" on the screen.  The mouse pointer is a
          graphic symbol, often shaped like an arrow, which slides over any text or
          other graphic on the screen.  While the mouse pointer is over a specific
          item pressing a mouse button selects or invokes a function represented
          by the item.  This allows a sighted user to "point" at the item or function to
          be used, then simply "click" to initiate the action.  However, it can be very
          difficult for a person who is visually impaired to quickly locate objects on
          the screen by simply moving the mouse pointer.  Objects on a Windows
          screen can change size or position as new information appears, and may
          even be partially hidden by other objects.  Furthermore, since Windows
          does not use the 80 by 25 screen matrix used by DOS, it can be difficult to
          quickly determine even the relative position of the mouse pointer on the
          screen.
          
          Although many DOS applications now give the user the option of using a
          mouse to issue program commands, most people tend to think of a
          mouse as an integral part of the Windows operating system. 
          ScreenPower for Windows makes it possible for a person who is visually
          impaired to take advantage of the simplicity and power of mouse functions
          without actually using a mouse.  The screen navigation commands (which
          will be discussed in detail later in this section) provide a way to move the
          mouse pointer in an organized, logical manner, then issue the mouse
          command from the keyboard.  
          
Elements of Windows
          
          When working with the DOS operating system, you form commands from
          a set of well defined key words according to strict syntax rules. 
          Commands begin with a verb specifying the action to be taken, then list
          the items to be acted upon.  For example, if you decide to delete a file
          from a floppy disk, you know exactly how to form the command.  First, you
          type "DEL" to specify the action to perform.  Next, you enter the drive
          specification and filename.  Finally, you press the Enter key to initiate the
          action.  
          
          Windows has a similar set of discrete elements which perform many of
          the same functions as their DOS counterparts.  However, in the GUI
          Windows environment, these elements are represented as graphic
          objects on the screen.  Instead of typing your command, you select the
          item which represents the action you wish to perform.  Windows then uses
          other objects to ask for any additional information it may need before
          initiating the action.  This can make it very easy to execute new or seldom
          used operations since Windows attempts to guide you through each step
          by displaying prompts and options.  However, just as a DOS user needs
          to know the rules for issuing commands, the Windows user needs to
          understand how to interpret and manipulate Windows screen elements.
          
          The following paragraphs will briefly describe some important Windows
          elements and their properties.  Although the names for these elements
          can vary somewhat from one Windows manual to another, the names
          described will be used consistently within the ScreenPower for Windows
          documentation.  Each section heading also shows the abbreviations used
          for these elements in the ScreenPower for Windows program.
          
          Windows (WI)
          
          In simple terms, a window is a framed region of the screen.  Thus, you
          could think of your computer's monitor screen as a window with very fixed,
          physical boundaries.  However, in the Windows operating system a
          window is a much more dynamic object.
          
          A window always has four borders, but these borders can shrink and
          expand to change both the size and shape of the window at any time. 
          Any number of windows may be placed on your screen at one time.  Since
          your monitor has physical limitations, some windows may partially or
          completely cover others.  However, Windows allows the user to "focus"
          on, and therefore work within, only one window at a time.  The window
          you are using is said to be "active" or "selected."
          
          Each window can be thought of as a sort of miniature screen.  In one
          window, an application such as WordPerfect could be running and this
          manual might be displayed.  In another, your personal finance manager
          might be displaying your current account balances while still another is
          listing all the files you could access on the disk in your floppy drive. 
          These three windows might all be the same size or the active one might
          be nearly as large as the entire screen.  In either case, you could quickly
          move from one to the other with a single Windows command.
          
          Just as your computer screen may contain several windows, a window
          may contain sub-windows.  This feature can help you organize your files
          and applications into logical "groups" for easy access.  This concept is
          somewhat similar to the DOS subdirectory structure and will be discussed
          in more detail later in this section.
          
          Although each window may have a different purpose and contain different
          objects, there are some items which are common to most windows. 
          Windows typically have a title bar, a menu bar, a control-menu box, sizing
          buttons, and a client area.  Each of these items will be described more
          fully in the following paragraphs.
          
          The Title Bar (TB)
          
          A window's title bar is displayed immediately below its top border line.  Its
          purpose is simply to identify the name of the window or the application
          currently running in the window.  Title Bars also contain the Control-menu
          Box and sizing buttons.  (See below for more information about the
          Control-menu box and the different sizing buttons.)
          
          The Control Menu Box (CMB)
          
          The Control-menu box is a small square item in the upper left corner of
          most windows.  When you select this item, you open a Control menu
          which lets you move, size, minimize, maximize, restore and close the
          window.  You can also use the Control Menu to switch to another
          application.
          
          Sizing Buttons (MIB, MAB, RB)
          
          In the upper right corner of most windows you generally find two triangular
          graphics.  One triangle points downward and is called the "Minimize"
          button.  The other, which points upward, is called the "Maximize" button.
          
          When you select a window's Maximize button, the window is expanded to
          fill nearly the entire screen.  This gives you access to as many lines of text
          or rows of objects as possible.  A minimized window is reduced to a
          graphical representation of the window (called an icon) with no contents of
          the window visible.  However, the window is not "closed."  If an application
          is running within the window, minimizing the window may make it
          impossible to read any information in the window, but the application is
          not halted.  (See "Icons" later in this section.)
          
          Once a window has been maximized, the Maximize button is changed to a
          "Restore" button.  Selecting the Restore button returns the window to its
          previous size.
          
          The Menu Bar (MB)
          
          The menu bar is generally displayed immediately below the title bar.  The
          menu bar is a standard windows menu in that their consistent format
          provides access to most of the major functions available within the
          window.  Thus, the menu bar for a word processing window would contain
          different options than one in a database window since different operations
          can be performed, but operation of the two menus would be the same.
          
          The Client Area (CA)
          
          The remainder of the window can be thought of as the client area.  Many
          different objects can be placed on this work surface.  The exact contents
          of any window's client area depends on the purpose of the window.  For
          example, a window in which a word processor is running may have little
          besides the text of a document in its client area.  However, a window
          which is being used to group together several sub-windows may contain
          only those windows.  Each window's client area should be treated and
          explored as a separate and unique element.
          
          Menus (MI)
          
          A Windows menu is functionally very similar to those you are accustomed
          to using in DOS applications.  That is, a list of related options is displayed
          on the screen and you use the arrow keys to move to the item you wish to
          select.  A distinct screen highlight is used to indicate to a sighted person
          which menu item is currently selected.  Once the item you want to select
          is highlighted, you press the Enter key to confirm your selection.
          
          Windows menus can be either vertical or horizontal.  That is, the menu
          items are listed either in a column or across a single line.  Windows
          assigns the Up and Down arrow keys to move through a vertical list and
          the Right and Left arrow keys to move across a horizontal menu.  
          
          When you are using a horizontal menu, you can often "pull down" a
          vertical menu from each of the horizontal menu items.  Thus, you could
          move to the right until you find the menu you wish to open, then move
          downward to view the sub-menu items.  This type of "pull-down" menu
          simply covers anything else on the screen until you make your selection or
          close the menu with the Esc key.  The menu then disappears.
          
          Short-cut Keys
          
          You can often open menus, select menu items or activate other controls
          by using a "short-cut" key.  A short-cut key is either a letter or the Alt key
          plus a letter which activates the menu option in a single keystroke.  Most
          menu items are displayed with a single character in the name underlined. 
          If the menu containing this item is open, you can select the item by typing
          the underlined letter.  If you wish to open a menu with its short-cut key,
          hold down the Alt key and press the underlined letter.
          
          Since it is difficult to show the underlined character or announce it with
          braille, ScreenPower for Windows always indicates the hotkey separately
          when it encounters one.
          
          Icons and Bitmaps (IC, BM, CE)
          
          An icon is a small graphic which is used to represent an application or a
          window.  Most icons also have a text label.  When a Window is minimized,
          the entire window disappears and is replaced by a picture or "icon" which
          provides a visual cue to a sighted user.  
          
          To work with an icon, you move the focus to the icon and select it.  This
          "expands" the icon to the application or window it represents.  
          ScreenPower for Windows can identify many frequently used icons.  It
          does this by analyzing the particular pixel pattern used to form the icon
          and assigning a name to this pattern.  A pixel pattern for an icon is called
          a "bitmap."  ScreenPower also allows the user to name or rename icons. 
          If an icon has an associated text label, ScreenPower also displays this
          label.
          
          Special controls may also be represented by bitmaps in Windows
          applications.  For example, a button bar in a word processing program
          may consist only of a series of pictures.  When you click on a particular
          picture, you cause an action to happen, such as save or print your current
          document.  ScreenPower also allows you to name and work with these
          bitmap images.
          
          The Insertion Point
          
          While you are entering information in a document, dialog box, or edit box,
          you will encounter what appears to be a standard DOS cursor.  However,
          Windows calls this cursor the "insertion point" and it behaves somewhat
          differently from a traditional cursor in some situations.  Its purpose,
          however, is to signify that Windows expects the user to type information
          and to indicate where this information will be placed.
          
          Dialog Boxes (DB)
          
          A dialog box is a special kind of window which appears when the user
          needs to provide information to an application.  A dialog box generally
          does not contain a menu bar, but there is always at least one element or
          button.  To move from item to item within a dialog box either press the
          Tab key or hold down the Alt key and press the underlined letter in the
          field name.
          
          Dialog boxes can contain text messages and several different types of
          controls.  At a minimum, a dialog box must contain at least one command
          button (see below) which allows you to acknowledge the text or message.
          
          Other controls let you enter specific information required by the dialog
          box.  Below is a list of the types of controls that can appear in a dialog
          box.  These controls can also appear in other types of windows.
          
          Once you have entered the requested information, you should select the
          appropriate command button to close the dialog box or continue with other
          options.
          
          Command Buttons (CMB)
          
          A command button is simply a oval shaped symbol which initiates some
          action which will be performed when pressed or selected.  When a button
          is displayed which cannot be used in the current situation, it is grayed out
          or "dimmed."
          
          Buttons are typically displayed as small circles which darken or become
          surrounded by a dotted frame when selected.
          
          Command buttons initiate an action as soon as they are selected.  Thus,
          an "OK",  "Start" or "Cancel" button has an immediate effect on program
          execution.
          
          Option Buttons (OB)
          
          Option buttons allow the user to select one, and only one, of several
          possible choices.  For example, in a telecommunication program, a group
          of option buttons may display the various baud rates your modem might
          use.  You would select the button which corresponds to your modem's
          capability.
          
          When you encounter a group of option buttons, you can move to the
          currently selected button by pressing the Tab key.  You can then use the
          arrow keys to move to each of the other buttons in succession.  Press the
          Enter key to make your selection.
          
          Many option buttons also allow the user to issue a short-cut key command
          as described in the section on menus.  That is, if a letter in an option
          button's name is underlined, you can select that button by holding down
          the Alt key and pressing the letter key.
          
          Edit Boxes (EB)
          
          An edit box is an area that allows you to type some text that provides
          information required by the dialog box. A edit box is typically used for a
          single information item such as a filename or search string.
          
          List Boxes and Dropdown List Boxes (LB, DLB)
          
          As its name implies, a list box presents a list of choices to the user and
          requests a selection.  The Up and Down arrow keys usually scroll through
          the list.  The focus is generally indicated to a sighted user by highlighting
          the selected item, but other graphic devices are sometimes employed.  
          
          A Dropdown List Box doesn't always present a list of items on the screen. 
          To see the list, you press Up or Down to make the list box appear on the
          screen.
          
          If more options are available than can be displayed in the list box, scroll
          bars are provided to allow quick access to these items.  (See Scroll Bars
          later in this section.)  You can also use the cursor, Home, End, Page Up
          and Page Down keys to move through the list.
          Check Boxes (CHB)
          
          Check boxes are used to indicate whether an item or option is turned on
          or off.  The option is selected or "on" when a check mark or "X" appears
          within the box.  An empty box signifies that the option is "off" or not
          selected.
          
          To check or uncheck a check box, use the Tab or Shift-Tab keys to move
          to the box, then press the Spacebar to toggle its current setting. 
          Alternatively, you can often accomplish this by pressing the indicated
          short-cut key command.  
          
          Group Boxes (Frames) (GB)
          
          Group Boxes are usually groups of similar controls collected together in a
          box surrounded by a frame of lines on the screen.  The most common
          type of controls to find in Group Boxes are option buttons and check
          boxes.  For example, a telecommunications program may group all the
          baud rate settings together in a single group box.
          
          Text and Labels (TX, LAB)
          
          Text and Labels are usually static messages that appear in dialog boxes
          and other windows.  Also, any text you enter as part of a document in a
          word processing program is considered a text item.
          
          Scroll Bars (VSB, HSB)
          
          Scroll bars are vertical or horizontal arrow-tipped lines which sometimes
          appear at the bottom or right edges of a window.  There are two types of
          scroll bars.  A scroll bar control can be used to set a variable option.  This
          control can be compared to the slider switch used to control the volume
          level on a cassette recorder.  The second type of scroll bar indicates that
          the window is not tall or wide enough to display all of its information.  This
          type of scroll bar provides quick access to the hidden information.
          
          To use a scroll bar, a sighted person selects a scroll box which is
          displayed somewhere on the scroll bar and drags it in the direction he
          wishes to move.  ScreenPower provides an alternative way for a person
          who is visually impaired to use this device in a different, but functionally
          similar manner.  This feature is described in the Reference Guide section
          of this documentation.
          
          Multiple Document Windows (MDW)
          
          A multiple document window is somewhat different from a standard
          window.  Although all windows may contain a wide variety of other objects
          such as icons, buttons, dialog boxes, or other windows, each of these
          items is generally an independent entity.  The sub-windows in a multiple
          document window, however, share objects and functions with their parent
          window.  Each sub-window has its own title bar, but generally uses the
          menu bar displayed in the parent window.
          
          For example, Program Manager uses Multiple Document Windows for
          each of the Group Windows.  Most popular full-featured word processing
          programs use Multiple Document Windows to hold the contents of each
          separate document you are working on.  MS Write, a word processing
          program provided with Windows does not use Multiple Document
          Windows because it allows you to have only one document open at a
          time.
          
          Combined Elements (CE)
          
          ScreenPower for Windows will often identify the objects in a window's
          client area as "combined elements."  This means each of the icons or
          bitmaps displayed in this area also has a related text label.  Both the
          bitmap definition and the label are identified when a combined element is
          encountered.
          
          
The Desktop
          
          The "desktop" is the starting point for all Windows activity.  It is the main
          work surface where any applications or data to be used must be placed. 
          Think of it as a main window which contains all other objects you wish to
          use.  
          
          You may place any application on the desktop.  For example, you may
          wish to have your word processor, a calendar, a calculator, and your
          address database on this main screen for easy access.  However, it is a
          good idea not to clutter the desktop with too many items.  Just as it is
          difficult to find things on your real desk when too many objects are piled
          on its surface, it can be difficult to find applications on a cluttered
          Windows desktop.
          
          
The Program Manager
          
          When you install the Windows operating system, a special application
          called the "Program Manager" is placed on the desktop.  The Program
          Manager contains all functions necessary for manipulating and using any
          other application or utility.  Other applications are installed within the
          Program Manager and organized into logical groups within sub-windows. 
          Thus, when you are exploring a Windows screen, the Program Manager 
          window is the most likely place to begin searching for a specific
          application.
          
          The menu bar in the Program Manager window contains a variety of
          useful object manipulation tools.  You should thoroughly explore this
          menu and become familiar with each option.  Many of these menu items
          will appear on the menu bars of other application windows.
          
          For more information about the Program Manager, consult your Windows
          manual.
          
          Program Manager has several sub-windows that are used to group related
          items together.  Several of these groups are described below.
          
          The Startup Group The Program Manager typically contains a special
          group item called "Startup."  Any application placed in this group will be
          started automatically each time you load the Windows operating system. 
          For example, adding the ScreenPower for Windows application icon to the
          Startup group causes your speech and/or braille access to be loaded
          each time you start Windows.
          
          The Main Group Another group item which is generally included in the
          Program Manager window is the "Main" group.  The Main window often
          contains several utilities which allow you to customize your windows
          working environment.  For example, the Control Panel allows the user to
          select default fonts and colors for objects on the desktop.  
          
          The Accessories Group The "Accessories" group usually contains a
          clock, a calculator, a text editor, and many other useful utility programs. 
          This group often serves as a holding area for these and many other small
          data management utilities developed for Windows users.
          
The Help System
          
          The Windows operating system contains an extensive Help System which
          can provide context sensitive information at any time.  To access the Help
          System, select "Help" from the menu bar or press the F1 key.  
          
          ScreenPower for Windows allows you to effectively use the Help System
          functions and to read the help screens.  You may find it very helpful to
          begin your exploration of Windows and ScreenPower by thoroughly
          investigating this utility.
          
Standard Windows Applications
          
          When you install the Windows operating system, several applications are
          automatically loaded into the Program Manager.  Although these
          applications will probably not meet all of your computing needs, you may
          find several quite useful.  Others are essential for effective window and file
          management.  
          
          The following paragraphs will briefly describe some standard Windows
          applications.  You may find it helpful to experiment with these applications
          while you are learning to use ScreenPower and becoming familiar with
          Windows's standard user interface.
          
          The File Manager The File Manager is another very important
          application which is always placed in the Program Manager Group Main. 
          The File Manager allows the user to perform disk and file maintenance
          commands similarly to those defined in the DOS operating system.  You
          use File Manager to format disks, to create sub-directories, and to
          manipulate files.  You can use File Manager to view the contents of a disk
          and to work with a specified group of files at the same time.  Refer to your
          Windows documentation or review the available information in the Help
          System to become very familiar with File Manager operations.
          
          Write Write is a limited word processing program provided with
          Windows.  It allows you to create, edit, and print documents.  Though it
          does not contain all the features found in other programs such as
          Microsoft Word and WordPerfect, it is often used to provide on-disk
          documentation for many applications.
          
          Minesweeper Minesweeper is a game found in Program Manager's
          Game group.  Minesweeper, though a very graphic game, can be played
          with ScreenPower for Windows using a braille display.  See "Part 3: Using
          ScreenPower for Windows" for instructions about playing with
          Minesweeper with a braille display.
          
          Other applications and utilities provided by Windows include Calculator,
          Calendar, Cardfile, Notepad and Terminal.  Each of the utilities provides
          basic functions that you may find useful.
          
          
How ScreenPower Provides Access To Windows
          
          ScreenPower for Windows allows a person who is visually impaired to
          work effectively with the Windows operating system by providing detailed
          information about all items on the screen.  The user can access as much
          or as little of this information as necessary at any time.  ScreenPower also
          allows the user to organize this information in a variety of ways to suit the
          specific application or task being performed.  However, a thorough
          understanding of the operating modes and organizational options is
          essential.
          
Focus Tracking
          
          As mentioned above, ScreenPower offers two different operating modes. 
          Both of these modes are active at all times and the user can move freely
          from one to the other as necessary.
          
          In "focus tracking" mode, the user interacts with Windows and Windows
          applications from the standard alpha-numeric part of the keyboard.  Only
          those keyboard commands which have been defined in Windows or the
          application are available.  That is, if the Windows manual tells you to use
          the Alt-Esc command to access a function, you would use this command
          and rely on ScreenPower to announce or display the result.  
          
          Although no special commands are used in focus tracking mode,
          ScreenPower for Windows provides essential information about the
          currently selected Windows element.  Each time the "focus" is moved to a
          new item, ScreenPower displays and announces as much relevant
          information as possible about the new object.  As a result, you can often
          move very quickly through familiar screens and applications.
          
Exploration with the Navigation Keys
          
          While you are learning Windows or getting acquainted with a new
          application, there will probably be times when you feel lost among the
          many objects on a Windows screen.  At these times, you can use the
          navigation commands and exploration mode to obtain as much
          information as you need about these objects.  The navigation commands
          are always active and can be used to obtain information about your
          current position at any time.  You could also use these commands
          exclusively to move through and interact with Windows screens. 
          However, once you learn the commands defined by your application, you
          will probably find it more efficient to work primarily with these keys.  
          
          All ScreenPower for Windows commands are issued from the number pad
          on the right side of the keyboard.  Since these keys are rarely used by
          standard Windows applications, this arrangement significantly reduces the
          risk of key conflicts.  This also provides a physical and conceptual
          separation between Windows and ScreenPower operations.
          
          When you first load the ScreenPower for Windows software, all of the
          keys on the number pad are used as navigation commands in the
          exploration mode.  They allow you to identify each item on the screen, to
          control mouse functions, and to obtain information about important screen
          attributes.  They also provide information about the organization of the
          objects on the screen.  Finally, the navigation commands help a person
          who is visually impaired move to and use Windows elements in a logical
          and efficient manner.
          
The Navigation Tree Model
          
          The navigation commands provide information about Windows screens by
          arranging screen elements into logical or functional groups.  Although the
          actual objects on the screen are not moved or changed, ScreenPower
          maintains an internal image of the screen in which items are organized
          into groups and sub-groups.  The navigation commands allow you to
          move from group to group, or help you to explore the items in a selected
          sub-group.  
          
          This internal image is called the "navigation tree" and you may find it
          helpful to compare this structure to the typical model of a tree.  If you think
          of the desktop as the single root of the tree, then each object placed on
          the desktop is a branch off of the root.  If one of the branches is a window
          which contains other windows or application icons, then these
          sub-elements are branches off of the original branch.  This model can be
          expanded to any number of levels until you eventually reach the specific
          object you wish to use.
          
          Although you probably don't think about it, you use this hierarchical, tree-like method of arranging information and objects each day.  For example,
          if you wanted to look up a specific command in this manual, you would
          first examine the chapter headings to determine which might contain this
          information.  You would then read through the sub-section titles within the
          selected chapter in an attempt to reduce the number of pages you must
          search still further.  Finally you would move to the specific sub-section
          where you should quickly locate the information.  
          
          By organizing Windows screen elements according to this tree structure,
          ScreenPower accomplishes two important tasks.  First, it offers a
          non-linear way to describe the screen in a concise, and useful manner. 
          Second, this structure provides a logical path from one screen element to
          another while maintaining a clear sense of screen orientation.  
          
          The navigation tree model will be used throughout the remainder of this
          manual to describe navigation functions.  For more information about this
          topic, please refer to the Part 3: Using "ScreenPower for Windows" or
          Chapter One of the Reference Guide.
          
Mouse Actions
          
          As you read the documentation provided with Windows and Windows
          applications, you will be directed to use a mouse for most operations. 
          However, in most cases, an alternative keyboard command is also
          provided.  Generally, you should use these keyboard commands and rely
          on ScreenPower's "focus tracking" ability to help you interact effectively
          with the application.  However, when a keyboard command is not provided
          or when it is more convenient to use a mouse, the navigation commands
          offer an alternative way to issue mouse commands.
          
          Windows uses a mouse to perform three primary tasks:
          
          1.   The movement of the mouse controls the position of the mouse
                         pointer on the screen.  The navigation commands in exploration
                         mode can also position the mouse pointer on the selected item.
          
          2.   By clicking or double clicking a mouse button, the user can select
                         items or initiate actions.  The Center or "5" key on the number pad
                         can be used to issue these commands.  To "click" simply press and
                         immediately release this key.  To "double click", press and release
                         the key twice in rapid succession.
          
          3.   By holding down a keyboard key while moving the mouse, objects
                         on the screen can be moved to a new position.  ScreenPower
                         offers alternative methods for performing these functions.  For
                         more information about this type of mouse action, see "Drag and
                         Drop" functions in the Reference Manual.
          
Keypad Layers
          
          As we have already discussed, all ScreenPower commands are issued
          from the number pad on the right side of the keyboard.  While this
          arrangement has many advantages, there are far too few keys on the
          number pad to support the many options available in the ScreenPower for
          Windows software.  To solve this problem, ScreenPower uses the concept
          of keypad "layers" or overlays.
          
          ScreenPower uses ten keypad layers.  To select a layer, you press the "0"
          key on the number pad then a digit between 0 and 9 which corresponds to
          the layer you wish to use.  Once you have selected a layer, each key on
          the number pad is assigned to a completely unique function.  Thus, you
          have ten possible sets or sub-menus of commands available.
          
          Layer 0 is the default layer.  It contains the navigation commands for
          exploration mode and should be selected during normal operation.  The
          other layers contain commands for changing output options, alternative
          Windows commands, and performance customization controls.  See the
          Tutorial and  Reference Guide for more information about using the
          Keypad Layers.
          
          
Getting Help
          
          This manual can be read on-line at any time using the Windows Help
          system.  It is provided as a standard Help program.

                              Part Two: Installation Guide
          

This section provides instruction for installing your ScreenPower for
Windows software.  Before you begin, you should make sure all your
hardware (braille display and speech synthesizer) and supporting software
as well as Windows 3.1 are installed and functioning properly.

If you are using Gateway, ScreenPower Braille, ScreenPower Speech or 
ScreenPower Integrated for DOS, you should also make sure they are
installed and working properly.

If you are planning on using speech without ScreenPower, make sure any
synthesizer drivers are loaded and working in DOS.

If you are planning on using an SSIL synthesizer driver, you should make
sure the synthesizer is installed and working at DOS.


System Requirements

ScreenPower for Windows requires the following:

     A 386 or 486 computer running Windows 3.1 or 3.11

     A 1.44 MB High Density 3.5 inch floppy drive

     3 MB available on your hard disk

     Minimum of 6 MB of memory

     DOS version 3.3 or later.

ScreenPower for Windows also requires either:

     A supported TeleSensory braille display (PowerBraille 40, David,
     INKA, DM80, Navigator 80 or Navigator 40).

     A synthesizer supported by TeleSensory's ScreenPower Speech
     for DOS program and ScreenPower for DOS.

     or

     An SSIL supported speech synthesizer.
          
          Since ScreenPower for Windows is a Windows application, best
          performance can be achieved by the same requirements that improve
          general Windows performance.  These include using a fast video adapter,
          a fast hard disk and installing 8-20 MB of memory.
          
          ScreenPower's performance benefits from an additional 2 MB of memory
          above the minimum requirements of you application.  For example, if you
          have an application the requires 8 MB memory, ScreenPower
          performance will be enhanced if you install 10 MB of memory.
          
          
Screen Power for Windows Software Installation
          
          You should receive the following disks in your ScreenPower for Windows
          package:
          
               3.5 inch Program Disk
          
               3.5 inch TeleSensory Driver Disk
          
               3.5 inch SSIL Driver Disk
          
          Make sure you have all three disks available before you start the
          installation.
               
          The Screen Power for Windows Program Disk you receive has
          compressed files on it.   During the installation process the files will be
          "uncompressed" and placed on your hard drive in usable format.  If you
          have questions about the files on your disk, complete the software
          installation process so that the files are restored.  Then you can look at all
          of them.  
          
          If you experience any problems during the installation process,
          please call TeleSensory Technical Support at 415-960-0254.
          
Using the Installation Program
          
          1.   Starting the Installation Program
          
               Start from the DOS prompt, usually C:\>.
          
               Put the Screen Power Program diskette in drive A or B.
          
               Type A: or B: and press Enter.   
          
               Type INSTALL and press Enter.
          
               The computer displays a screen with two menu items welcoming
                         you to the installation program and asking you if you want to install
                         or exit.  Press Enter to continue with the installation.  Press X to
                         abort the installation.
          
               Note:     You can press Ctrl-C at any time to abort the installation.
          
          2.   Selecting a Directory
          
               The installation program asks if you want to install Screen Power in
                         the default directory or if you want to choose your own directory. 
                         Unless you have some particular reason to want your Screen
                         Power files elsewhere, press Enter to accept the default directory,
                         C:\SPWIN.
          
               If you want to specify another drive or directory, backspace over
                         the current entry, then type the full drive and directory name and
                         press Enter.  If the directory you entered already exists, the install
                         program warns you that Screen Power files may replace files that
                         already exist in the directory.  Press Enter to type in a new
                         directory.  Press Down Arrow, then Enter if you want to accept the
                         original directory.
          
          2.   Specifying Hardware
          
               Specify which type of output device you plan on using with
                         ScreenPower for Windows.  The options are Braille Only, Speech
                         Only or Braille and Speech.
          
               Braille Only If you specify Braille Only, the installation program
                         needs to know what type of braille access you are using.  
               If you are using Gateway software with Navigator displays, select
                         Gateway.  
          
               If you are using ScreenPower Braille with either PowerBraille or
                         Navigator, select ScreenPower.  
          
               If you are using any other supported braille display, select Other. 
                         Then follow the menu prompts to select the device you are using.
          
               Speech Only If you specify Speech Only, the installation program
                         needs to know what type of speech access you are using.  
          
               If you are using ScreenPower Speech, select ScreenPower.  
          
               If you are using any other supported speech device, select Other. 
                         Then select the device you are using. You will be prompted to
                         insert the TeleSensory Driver disk. 
          
               If you are using an SSIL supported device, select SSIL.  The install
                         program prompts you to insert the Arkenstone SSIL driver disk in
                         the drive.  Insert this disk now.  Then use the Up and Down arrow
                         keys and press Enter to select your synthesizer from the list
                         presented.
          
               Braille and Speech If you specify Braille and Speech,  the
                         installation program needs to know what devices you are using.  
          
               If you are using Gateway software with Navigator displays, select
                         Gateway.  
          
               If you are using any version of ScreenPower, select ScreenPower.  
          
               If you are using any other supported braille display, select Other. 
                         Then follow the menu prompts to select the braille device you are
                         using.
          
               Next you will be prompted for the speech device you are using. 
                         Select your device from the menu.  You will be prompted to insert
                         the TeleSensory Driver disk.
          
               If you are using an SSIL supported device, select SSIL.  The install
                         program prompts you to insert the Arkenstone SSIL driver disk in
                         the drive.  Insert this disk now.  Then use the Up and Down arrow
                         keys and press Enter to select your synthesizer from the list
                         presented.
          
          3.   Copy and Uncompress Files
          
               After you have selected your hardware devices, the install program
                         asks you to reinsert the Program Disk.  The install program then
                         copies all necessary files to your hard disk and uncompresses
                         them.  This can take a few moments.
          4.   Modifying Your Windows Start-up Files
          
               The next screen in the installation program (titled "Modify Windows
                         Start-up Files") asks if you want to add the ScreenPower for
                         Windows automatically when Windows loads.
          
               If you want ScreenPower to start automatically when you load
                         Windows, you should select the default "Modify Windows Start Up
                         Files."  
          
               If you don't want ScreenPower to start automatically when you load
                         Windows, you should select the "Do Not Modify Start Up Files"
                         setting.  To make this selection, press the Down Arrow key, then
                         press Enter.  
          
               Selecting the Windows Directory The installation program
                         needs to know which directory you use for Windows.  Normally, this
                         is C:\WINDOWS.  If this is correct, press the Enter key to accept
                         the directory.  If your Windows directory is not C:\WINDOWS,
                         Backspace of the existing entry and enter the correct directory,
                         then press Enter. 
          
          5.   Completing the Installation
          
               You have now completed the installation.  Screen Power will create
                         a batch file called SPWIN.BAT that runs the correct Screen Power
                         files for your synthesizer.  This batch file will be in both the root
                         directory and whichever Screen Power directory you designated
                         (the default is \SPWIN).  
          
               A final screen tells you to press any key to exit the installation
                         program.  When you do that, you will go back to the DOS prompt. 
          
          Congratulations!
          
          You have successfully installed your ScreenPower for Windows system. 
          See the next section, "Starting ScreenPower for Windows," for
          instructions on how to run ScreenPower for Windows.
          
          
Starting ScreenPower for Windows
          
          If you chose to have the ScreenPower installation program modify your
          Windows start-up files, then Windows will load ScreenPower automatically
          whenever you start Windows.  However, in some cases, special files must
          be loaded before Windows start.  To make sure ScreenPower for
          Windows loads correctly, type
          
                    SPWIN
          
          and press Enter at the DOS prompt whenever you want to start Windows. 
          Windows will load and ScreenPower will start automatically.  
          
          Note:  If you are using ScreenPower for DOS or any SSIL supported
          synthesizer that requires special drivers be loaded in memory, make sure
          those drivers are loaded before you start Windows.
          
          For example, the DECtalk and DECtalk Express require DOS programs
          be run before another program can communicate with the synthesizer.  Be
          sure these files are loaded before you start Windows.
          
          If you are using ScreenPower for DOS, be sure ScreenPower is loaded
                    and working before running Windows.              Part Three: Using ScreenPower For Windows
          
This section of the manual is designed to familiarize you with how
ScreenPower for Windows works through a series of short lessons.  The
best way to use this section is to read through the steps in each lesson to
be sure you understand what you are trying to accomplish.  Then perform
the steps as you read through them.

As you work through the lessons, take your time.  If you get lost or are not
sure what is happening, try starting over.  Though easy to use, Windows
is a very complex environment that allows several tasks to happen at
once.  It is very easy to accidentally switch from one task to another. 
Since no two Windows setups operate identically, it is possible to move
into areas not covered in the lesson.


Learning About Windows

Before we begin learning about ScreenPower For Windows, it is important
to understand more about how Windows works.  We have included a set
of tapes and raised line drawings called "Opening Windows."  This
introduction to Windows was created by Doug Wakefield for the United
States Government Clearinghouse for Computer Accommodation and is
provided by TeleSensory as a courtesy at no additional cost.

Take the time to listen to these tapes now.  Do not worry about reviewing
the screens or trying to access information with ScreenPower while you
are listening to the tapes.  Your goal is to understand and learn more
about how Windows itself functions.  

When you have completed the tapes, continue with this section of the
manual.  In the each of the following lessons, we will teach you concepts
about how ScreenPower for Windows functions in the different areas of
Windows.

Each lesson provides a description of the concepts covered in that lesson. 
If any setup is needed a short setup section is provided.  This may involve
commands that may not make sense at first but allows the lesson to start
in the correct place without requiring a lot of explanation.

After the setup, each lesson consists of a series of steps.  In each step
you are told what keys to press, what should appear on the braille display,
what you should hear, and a description of what is happening in that step
of the lesson.  If a speech or braille only command is available during the
          step, it will be presented under the heading Braille Users Tip or Speech
          Users Tip. At the end of each lesson is a summary of what was presented
                    in that lesson.Lesson 1: Basic Navigation Concepts
          
          ScreenPower for Windows provides access to Windows information in two
          different ways, through Focus Tracking and Exploring.
          
          Focus Tracking is what you were doing when you where listening to
          "Opening Windows."  The focus is what Windows moves on the screen as
          you give commands to Windows.  The speech and braille output follow
          the focus providing information each time the focus changes.
          
          The second way to access Windows is to Explore with the ScreenPower
          navigation keys.  These keys are all located on the ten key pad of the
          standard 101-key keyboard.
          
          ScreenPower uses a hierarchal approach to accessing Windows.  The
          Exploration commands allow you to explore Windows without knowing any
          Windows commands.  As you Explore, Windows is actively following
          along with you.  When you get where you want, you can immediately
          perform the action required to continue.
          
          ScreenPower uses a unique approach to navigating and exploring
          Windows.  In the past, text based systems followed some basic rules and
          it was usually possible to quickly determine a screen layout.  For example,
          most screens were 80 characters wide and 25 lines long.  Each character
          took up the same amount of space and it was possible to always
          determine the relationship of one character to another.
          
          In Windows, these basic rules no longer apply.  Characters and pictures
          can appear anywhere on the screen.  Relationships between characters is
          harder to determine.  Information does not have to appear in neat lines of
          text.  The next character in a string can start half a line down the screen if
          the programmer wants it to do so.
          
          In text-based applications menus usually had a single line of text that you
          could read and select.  In Windows, choices can be presented as a series
          of pictures with or without text labels attached.  They can take up small
          areas on the screen that are several lines tall.
          
          Since the information in Windows can be presented in so many ways,
          traditional ways of reading screens do not make as much sense as they
          did in DOS.  Reading a screen or window from the upper left to the lower
          right corner in a line-by-line manner may provide you all the text and
          pictures in the window, but it may not provide you with the relationships
          between the different elements.
          Instead of treating each window as a DOS screen, reading it from the top
          down, left to right, ScreenPower breaks the screen down into elements. 
          Where a text label and a list of items are two pieces of one Window
          control, ScreenPower links them together, treating them as a single
          element.
          
          Windows may display elements on the screen in any direction.  In a single
          window, some elements may be arranged vertically and others
          horizontally.  Labels can be to the left or right, on top of the element or
          below it.
          
          Since there is so much diversity in screen layouts, ScreenPower
          navigates from element to element.  When you reach an element, you can
          get more information about the pieces that make up that element.
          
          In this lesson we will look at the four basic navigation keys and how they
          are used to move through the ScreenPower navigation tree from element
          to element.  The four keys are located on the number pad keys 2, 4, 6,
          and 8.  These keys are used to Explore In and Out, Up and Down in the
          ScreenPower navigation tree.  Later we will also use the 5 key to perform
          mouse clicks.
          
          ScreenPower uses only the keys on the number pad  located on the right
          side of the standard 101-key keyboard.  ScreenPower commands are
          identified by their function and their corresponding key on the number pad
          in parenthesis.  For example, if you are told to press the Explore Out key
          (4), press the "4" key on the keypad.
          
          Setup:    Start Windows and load ScreenPower for Windows.  See
                              the instructions at the end of Part 2: Installation Guide if you
                              are not sure how to do this.
          
                    Press the Explore Out key (4) until you are at the Desktop.
          
                    The Desktop is a good starting place for learning to navigate
                              Windows.  Think of it as the ultimate element, one that
                              contains all other elements in Windows.  From here you can
                              begin to explore what your Windows environment looks like.
          
          Step 1:   Press the Explore In key (6).
          
                    What you should read?    Info WI: IC WI
          
                    What you should hear?    Info: Icon Window
          
                    What's Happening?
          
                    Pressing the Explore In key gives you information about the
                              Desktop.  Any time you Explore In from an element, the first
                              thing you encounter is an Info Line that tells you more about
                              the element you are exploring.  Usually this is a list of
                              elements that can be explored further.  In this case,
                              ScreenPower is telling us that the Desktop contains an icon
                              and a window.
          
                    ScreenPower uses abbreviations on the braille display so
                              that more information is displayed.  Though the
                              abbreviations can be turned off, we will look at how to do
                              that later.  For now, whenever an abbreviation is
                              encountered in the lesson, we will tell you what it means.
          
                    Also, during the lessons, the output from your system may
                              be different than stated.  Windows can be set up in many
                              different ways.  We are assuming a standard Windows
                              setup, though even this will have differences from system to
                              system.  In this step, ScreenPower may tell you that you
                              have more windows or icons on your desktop. But for the
                              most part, the information presented by ScreenPower during
                              these lessons should be similar to your system.
          
          Step 2:   Press the Explore Down key (2).
          
                    What you should read?    IC 1 Braille Print
          
                    What you should hear?    Icon Braille Print
          
                    What's happening?
          
                    The Explore Down key lets you navigate down the list of
                              elements originally presented on the Info Line.  Each time
                              you press the Explore Down key, you move to a new
                              element.
          
                    Braille Users Tip The braille display shows a number after
                              the element name.  It tells you the number of the current
                              element types. This helps when you start navigating areas
                              that have many of the same type of element.  This feature
                              can be turned off if you like.  See the Reference Guide for
                              more information.
          
          Step 3:   Press the Explore Down key (2) again.
          
                    What you should read?    WI 1 Program Manager
          
                    What you should hear?    Window Program Manager
          
                    What's happening?
          
                    You have Explored Down to the next element contained on
                              the Desktop.  If you have more elements, you could continue
                              to press the Explore Down key to see each of them.  You
                              could also press the Explore Up key (8) to go back up the list
                              to the Info Line.
          
          Step 4:   Press the Explore Out key (4).
          
                    What you should read?    Desktop
          
                    What you should hear?    Desktop
          
                    What's happening?
          
                    Anytime you Explore Out from an element, you return to the
                              element that contained it, in this case the Desktop.
          
                    You would have reached the Desktop from any of the
                              elements listed below it, including the Info Line
          
          Summary:  In this lesson, you have used the four basic navigation
                              commands for ScreenPower for Windows.  These are
                              Explore In (6), Explore Out (4), Explore Down (2), and
                              Explore Up (8).  The Explore In key moves you deeper into
                              the navigation tree, getting more information about each
                              selected element.  The Explore Out key moves you out of
                              the branches of the tree, closer to the Desktop.  The Explore
                              Up and Down keys allow you to move among elements that
                              exist on the same branch of the tree.
          
                    Lesson 2:  Exploring Windows
          
          In this lesson we will practice the navigation keys to find the word
          processing application called Write, open it and switch back to Program
          Manger.  We will teach you some navigation shortcuts for braille users
          and how to execute a mouse click.
          
          Note: If you are using a System 90 product (David, INKA, or DM80) make
          sure the optical sensors are active by setting switch 4 to the left.
          
          Setup:    Press the Explore Out key (4) until you are at the Desktop.
          
                    Press the Explore In key (6) once to the Info Line, then the
                              Explore Down key (2) until you reach a window called
                              Program Manager.  
          
                    Press Alt-Space, X to maximize the Program Manager
                              Window.
          
                    Press the Explore Out key (4) until you are back at the
                              Desktop.
          
                    Note:  Because of the many ways windows can be set up,
                              your Program Manager groups may be minimized as icons. 
                              Any time we refer to a window and your system calls it an
                              icon, quickly press the 5 key twice on your keypad to open
                              the window.
          
          Step 1:   Press the Explore In key (6).

                    What you should hear     Info: Icon Window
          
                    What's happening?
          
                    This is the Info Line. It provides you with a list of objects that
                              make up the Desktop.  In this case it is telling you that there
                              is one window and one icon on the desktop.  Later, the Info
                              line will give you information about elements other than the
                              Desktop.
          
          Step 2:   Press the Explore Down key (2) until you reach the Program
                              Manager window.

                    What's happening?
          
                    As you press the Explore Down key, ScreenPower describes
                              each element contained on the Desktop.  These are the
                              same elements that were listed on the Info Line.  Rember, if
                              you heard IC Program Manager, click the (5) twice quickly.
          
          Step 3:   Press the Explore In key (6).
          
                    What you should read:    Info  Program Manager: TB MB
                                                       WI5

                    What's happening?
          
                    This is another Info Line, this time giving you information
                              about the Program Manager Window.  It tells you the list of
                              elements (a title bar, a menu bar and 5 windows) contained
                              in the Program Manager window.
          
          Step 4:   Press the Explore Down key (2) until you reach the Program
                              Manager Group Accessories.  If you should pass the
                              Accessories Group, use the Explore Up key (8) to back up
                              the list.

                    What's happening?
          
                    The number associated with the window or icon depends
                              solely on you individual system and will change from time to
                              time as icons become windows or windows become icons.
          
                    This time you are navigating through a list of elements
                              contained in the Program Manager window.  Again, these
                              are the same elements that were announced to you on the
                              Info Line for the Program Manager window.
          
          Step 5:   Press the Explore In key (6).

                    Note: In some cases ScreenPower may also indicate that a
                              scroll bar is present also.
          
                    What's happening?
          
                    Notice we are repeating the same steps; Explore In, Explore
                              Down.  This is a result of the navigation tree ScreenPower
                              uses.  Each element of the tree contains objects, which in
                              turn contain more objects.  When you Explore In, you learn
                              more about an element.  When you explore Down, you can
                              learn more about each of the objects contained in that
                              element.
          
          Step 6:   Press the Explore Down key (2) until you reach the Client
                              Area.
          
                    What you should read:    CA Group Accessories

                    What's happening?
          
                    Most applications have a Client Area.  It is usually the work
                              space where the application performs its main functions.  In
                              Program Manager, the client area is the place where it
                              stores all the program items for a group.  In a word
                              processor, the client area is usually the area where you want
                              to enter and edit text.
          
                    Since Program Manager can have lots of groups and each
                              group is a window, there are lots of client areas.  A word
                              processor that can have several documents open at once
                              will also have several client areas, one for each open
                              document.
          
          Step 7.   Press the Explore In key (6).
          
                    What you should read:    Info: CE #

                    What's happening?
          
                    You are now looking at the contents of the client area. 
                              ScreenPower is telling you that it contains a number of
                              Combined Elements.  Combined Elements are objects that
                              are made up of two separate elements that appear visually
                              to be a single element.  For example, these combined
                              elements are made up of a picture, or bitmap, and a text
                              label.  
          
                    Most other Windows access products will have you navigate
                              each of these objects separately, even though visually they
                              appear to be a single element.  ScreenPower knows that
                              these should be treated as a single element, and combine
                              them to make it easier to navigate.
          
          Step 8:   Press the Explore Down key (2) until you reach the Write
                              combined element.

                    What's happening?
          
                    Your are now on the Write program item.  The braille display
                              shows you that there is a Bitmap attached to this element
                              and it is not defined.  It uses the symbols [BM?] to indicate
                              this.  The speech just tells you the text label.  There are
                              ways to get more information about this element if you are a
                              speech only user.  (See Attribute Info Dialog Box in the
                              Reference Section)
          
          Step 9:   Press the Mouse Click key (5) twice quickly as if you were
                              double-clicking a mouse button.
          
                    What you should read:    Dots 7,8 and a funny symbol
          
                    What you should hear:     Window Write Untitled Cursor
          
                    What's happening?
          
                    Each time you open a window, ScreenPower tells you the
                              name of the window and the place where the focus ends up. 
                              In this case the name of the window is Write Untitled (the
                              Write document has not been named yet) and the focus is
                              the cursor.
          
                    The braille display shows the cursor (dots 7 and 8) and the
                              Write End of File Indicator (Dots 1, 3, 5).  At this point you
                              could begin typing to create a letter.
          
                    We are going to stop this lesson here.  Later we will work
                              more with text entry in the Write program.  Next we will look
                              at using ScreenPower's explore keys to navigate Program
                              Manager menus.
          
          Summary:  During this lesson we learned how to:
          
                    Navigate to an Icon
          
                    Click an icon to turn it into a window
          
                    Double-click the mouse with ScreenPower commands.
          
                    Exploring In always takes us to an Info Line.
          
          
                              Lesson 3: Exploring Windows Menus
          
          The easiest way to use Program Manager menus is with the menu
          hotkeys as described in "Opening Windows."  However, when you start
          using a new application, you may want to explore that application using
          the Explore keys.  This next set of steps will give you more experience
          navigating the ScreenPower tree and using Window's menu system.  You
          will also learn how to scroll the braille display for long lines.
          
          Setup:    You should still be in the Write application from the previous
                              section.  Press Alt-Tab to switch from Write to Program
                              Manager.
          
                    What you should read:    CE 1 [BM?] Write
          
                    What you should hear:    Window Program Manager, Write
          
                    What's happening?
          
                    The Write application is still running, but we have told
                              Windows that we want to switch to the Program Manager
                              without closing Write.  Later we will be able to switch back to
                              Write without having to explore and open it again, using
                              Windows hotkey commands.
          
          Step 1:   Press the Explore Out key (4).
          
                    What you should read:    CA Group Accessories
          
                    What you should hear:    Client Area Group Accessories
          
                    What's happening:
          
                    By exploring Out from an object, you move back one level in
                              the tree to the element that contained the object you were
                              on.  In this case, you moved back to the Client Area that
                              contained the Write program item.
          
          Step 2:   Press the Explore Out key (4) again.
          
                    What you should read:    WI 4 Group Accessories
          
                    What you should hear:    Window Group Accessories
          
                    What's happening?
          
                    Exploring out again takes you back another level, this time to
                              the Window Group Accessories.  This is the window that
                              contains the client area that contains the program item
                              Write.  Remember, pressing the Explore Out key moves you
                              backwards in the tree, closer and closer to the Desktop.
          
          Step 3:   Press the Explore Out key (4) once more.
          
                    What you should read:    WI 2 Program Manager
          
                    What you should hear:    Window Program Manager
          
                    What's happening?
          
                    You have moved back in the tree to the Program Manager. 
                              At this point we should start exploring back in to find the
                              Program Manager Menus.  But let's look at what happens if
                              we explore out one more level
          
          Step 4:   Press the Explore Out key (4) one final time.
          
                    What you should read:    Desktop
          
                    What you should hear:    Desktop
          
                    What's happening?
          
                    You are now back at the Desktop.  Remember, this is a
                              good starting point for all navigation with ScreenPower
                              commands.  If you find yourself getting lost among the many
                              windows and applications you are using, just press the
                              Explore Out key until you reach the Desktop, then start
                              exploring back in again.
          
                    Before we explore back in and start looking for the Program
                              Manager menus, remember what we learned about the
                              desktop last time.  ScreenPower told us there was one
                              window and one icon on the Desktop.  Notice the difference
                              this time during the next step.
          
          Step 5:   Press the Explore In key (6).
          
                    What you should read:     Info WI: WI2 IC
          
                    What you should hear:    Info Window 2 Icon
          
                    What's happening?
          
                    ScreenPower is telling us that there are now two windows
                              open on the desktop, as well as one icon.  You should notice
                              a couple of things here.  First, when you explore out, then in
                              again, you do not come back to the exact place you left. 
                              Exploring In always places you on an Info Line that lists the
                              objects contained in that element.  Exploring Out skips the
                              Info Line and takes you the next level up.
          
                    Secondly, you have two windows on the desktop instead of
                              just one.  Where did the second window come from?  Use
                              the Explore Up and Down keys to read through the list.  You
                              should find a window called Write Untitled.  Remember, after
                              we opened Write last time, we didn't close it; we left it open
                              and switched back to Program Manager.
          
          Step 6:   Explore Up and Down until you reach the Program Manager
                              Window. Press the Explore In key (6).
          
                    What you should read:    Info Program Manager: TB MB
                                                       WI5
          
                    What you should hear:    Info Program Manager Title Bar,
                                                       Menu Bar, Window 5
          
                    What's happening?
          
                    This should seem familiar.  We've been here before.  Last
                              time we looked for the Accessories Group window.  This
                              time we want the menu bar.
          
          Step 7:   Press the Explore Down key (2) until you get to the Menu
                              Bar element.
          
                    Braille Users Tip Instead of using the Explore keys, press
                              the Touch Sensor above either the letter "M" or "B" in the
                              Info Line.
          
                    What you should read:    MB Program Manager
          
                    What you should hear:    Menu Bar Program Manager
          
                    What's happening?
          
                    If you are using a braille display, the Touch Sensors allow
                              you to jump quickly to any item listed in an Info Line.  Use
                              this feature to speed up navigation of the tree.
          
          Step 8:   Press the Explore In key (6).
          
                    What you should read:    Info MB  F O W H: File Options
                                                       Window Help
          
                    What you should hear:    Info: F O W H File Options
                                                       Window Help
          
                    Braille Users Tip This is a rather long Info Line and some
                              of the characters may not fit on the braille display.  To see
                              the rest of the display, press the "9" key on the keypad.  To
                              back the display up press the "7" key.  You can also use
                              keys on the braille display (Scroll Forward or Back on the
                              PowerBraille 40 or Display Buttons 2 and 5 on System 90
                              products).
          
                    What's happening?
          
                    This time the Info Line is showing us more information than
                              we've seen before.  The characters "F", "O", "W", and "H"
                              are the hotkeys for jumping to a menu item.  They stand   for
                              File, Options, Window and Help.  Then each of the menu
                              items is listed.
          
          Step 9:   Press the Explore Down Key until you get to Help Menu.
          
                    Braille Users Tip Don't forget you can jump right to the
                              Help menu by pressing the Touch Sensor above the letter
                              "H".   You can also press any of the Touch Sensors above
                              the word "Help."
          
                    What you should read:    MI 4 H Help (SM)
          
                    What you should hear:    H Help Submenu
          
                    What's happening?
          
                    ScreenPower is telling you the shortcut key for the item ("H"
                              in this case), the name of the menu item and that it has a
                              submenu attached to it.  The braille display also shows the
                              characters "MI 4" to indicate this is Menu Item 4 of the
                              Program Manager Menu Bar.
          
                    ScreenPower always lets you know the shortcut key for an
                              item. The next time you want  to get to the Help Menu while
                              working in Program Manager, you could press Alt-H,
                              avoiding the need to explore through the tree to the menu.
          
          Step 10:  Press the Explore In key (6).
          
                    What you should read:    Info MI   C S H W A: Contents 
                                                       Search for Help on... How to Use

                    What's happening?
          
                    This information is in the same format as you saw earlier
                              when you first encountered the Menu Bar.  ScreenPower is
                              showing you the contents of the Help Menu.  Remember,
                              braille users can use the Scroll Display Forward (9) and
                              Back (7) to read the rest of this information on the display.
          
                    From here you could continue to Explore Down, then In to
                              learn more about each of these menu items.   Or you could
                              explore out to one level and move up and down to other
                              menu items.  When you find a menu you want to look at,
                              Explore In to see what it contains.
          
          Practice: Explore the other menu items on your own.  To avoid getting
                              lost, be careful when you use the Explore Out key to avoid
                              moving out past the Menu Bar Program Manager element.
          
                    Also avoid Exploring In to items that have dialog boxes.
                              ScreenPower will tell you about these items as you
                              encounter them.
          
          Summary:  In this lesson you have learned to:
          
                    Explore and use Program Manager Menus
          
                    Read braille information that is longer than the display (007
                              and 009)
          
                                                  Jumping to elements using the Touch Sensors.Lesson 4: Finding Out Where You Are
          
          There are two commands designed to help you if you get lost.  In this
          lesson we look at the "Path Display" option and the "Jump to Info Line"
          command.
          
          Setup:    Move ScreenPower to the Help menu from the menu bar.
                              Then navigate to the About Program Manager Menu Item.
          
          Step 1:   Press the Path Display key (3).  ScreenPower outputs
                              something similiar to what is shown below, depending on
                              where you are in the tree.
          
                    What you should read:    Path \MI A About Program
                                                       Manager... \MI H Help \ MB \WI
                                                       Program Manager \Desktop
          
                    What you should hear:    Path: A About Program Manager
                                                       H Help Program Manager
                                                       Desktop
          
                    Primarily designed for use with a braille display, this
                              command lists the elements as it backs up the tree to the
                              Desktop.  In the current example, ScreenPower tells you
                              which submenu you are on, then the menu name in the
                              window Program Manager on the Desktop.
          
          Step 2:   Press the Path Display key (3) again to turn off the Path
                              display.
          
                    What you should read?    MI 5 A About Program Manager...
                                                       (DB)
          
                    What you should hear?    A About Program Manager has
                                                       dialog box
          
                    What's happening?
          
                    The Path Display command is a toggle command.  This
                              means that you enter it once to turn it on and enter the same
                              command again to turn it off.  You can also turn the Path
                              Display command off by pressing nearly any other key.  The
                              Path Display command is a special function that does not
                              make any sense if left on all the time.  ScreenPower is smart
                              enough to turn the Path Display off if you move the focus or
                              enter any other ScreenPower command.
          
          Step 3:   Press the Jump to Info Line key (1).

                    What's happening?
          
                    The Jump to Info Line command moves you to the top of the
                              list of items displayed in the current branch of the tree.  You
                              can accomplish the same thing by pressing the Explore Up
                              key (8) repeatedly.  This allows you to find out easily what's
                              contained in the current level if you have forgotten or gotten
                              lost.  Press Explore Down (2) to get back to "About Program
                              Manager" if you want
          
          Summary:  In this lesson you have looked at two commands designed
                              to help you navigate faster and give you information about
                              where you are.  The Path Display command lists the
                              elements you are in back to the Desktop.  The Jump to Info
                              Line quickly moves you to the top of the current element list
                                                            so you can begin to navigate from a known position.Lesson 5: Using Keypad Layers
          
          ScreenPower contains many commands that are provided in an easy to
          use arrangement on the keypad of the standard 101-key keyboard.. 
          Since Windows uses so many key combinations for its own use, the
          ScreenPower command structure avoids most keystroke conflicts.
          
          However, the standard keypad has only 17 keys on it.  We wanted to have
          more than 17 commands so ScreenPower uses the keypad in a unique
          way.  By using keypad layers, ScreenPower is able to have over 100
          commands, all given from the number pad. 
          
          In this lesson you will learn how to use the different keypad layers to give
          ScreenPower commands.  Using these commands, we will also learn how
          to find out what keypad layer is active, turn braille item abbreviation mode
          off and turn on attribute output for speech and braille.
          
          Setup:    None necessary.
          
          Step 1:   Press the "0" key on the keypad once.  Wait for a short
                              pause.
          
                    What you should read:    No changes to the braille display.
          
                    What you should hear:    Layer 0, Basic Functions
          
                    Speech Users Tip The different layers announce
                              themselves with speech output.  No output is generated for
                              the braille display.
          
                    What's happening?
          
                    When you press the "0" key by itself, ScreenPower waits for
                              a few seconds to see whether you press another key.  If
                              another key is not pressed during the short pause, then
                              ScreenPower announces the name of the current keypad
                              layer.
          
          Step 2    Press "02".
          
                    What you should read:    No changes to the braille display.
          
                    What you should hear:    Layer 2, Auxiliary Functions 2
          
                    What's happening?
          
                    When you press a number key after the "0" before the pause
                              ends, ScreenPower switches to the new keypad layer and
                              announces the name of the layer.  If you do not press a
                              number key quickly enough, ScreenPower will beep after a
                              short pause and stay on the active layer.
          
          Step 3:   Press "00".
          
                    What you should read:    No change to the braille display.
          
                    What you should hear:    Layer 0, Basic Functions
          
                    What's happening?
          
                    Since the basic navigation functions are on keypad 0,
                              pressing 00 returns you to the basic keypad.  At this point,
                              you can navigate again using the Explore Up, Down, In and
                              Out keys.  In the Reference Guide, we always refer to
                              commands by the number of the keypad and the key on that
                              pad.  For example, the next command we will look at is the
                              Abbreviations On/Off toggle.  The command to do this is on
                              keypad two, key one and is referred to as 021.
          
          Step 3:   Press "021" key on the keypad.
          
                    What you should read?    If you are on an element that
                                                       uses an abbreviation, the
                                                       element name should be
                                                       expanded.  Otherwise, no
                                                       change.
          
                    What you should hear?    Abbreviations Off
          
                    Speech Users Tip This command affects braille output
                              only.  If you are using speech only, the names of element
                              items do not change.
          
                    What's happening?
          
                    We have changed the Abbreviations option to expand
                              abbreviations.  If you are not on a element that uses an
                              abbreviation, press "00" and navigate to one now.  You'll
                              notice that only the main element of the Info line is
                              expanded.  The listed elements are not expanded.  Since
                              many elements can be shown at one time on an Info Line,
                              we have kept the abbreviations here.  But if you move down
                              from any Info Line, you'll see that the 2 or 3 character
                              abbreviation is now expanded.
          
          Step 4:   Press "021" again.
          
                    What you should read?    The element name should be
                                                       abbreviated.
          
                    What you should hear?    Abbreviations On 
          
                    What's happening?
          
                    This is another example of a toggle command.  The first time
                              you enter a toggle command, the function is turned on or off. 
                              When you enter the command a second time it resets back
                              to the default.
          
          Step 5:   Press "00" again to return to the basic keypad.
          
                    What you should read:    No change to the braille display.
          
                    What you should hear:    Layer 0, Basic Functions
          
                    What's happening?
          
                    If you are planning on using only one command in a keypad
                              layer, its a good idea to immediately switch back to the basic
                              keypad.  If you think of every command as a 5-digit number,
                              i.e. "02100" with the last two digits always "00," then you will
                              always have the basic navigation keypad active when you
                              are ready to navigate.
          
          Step 6:   Press "02700", then "02200"
          
                    What you should read:    No change to the braille display.
          
                    What you should hear:    Attributes On
          
                    What's happening?
          
                    This time we turned two functions on, one for braille and one
                              for speech. The 027 command turns on speech attribute
                              output and the 022 command turns on braille attribute
                              output.  Now when ever you encounter characters that are
                              highlighted, bold, italic, etc. the speech announces the
                              attributes and the braille turns on dots 7and 8 to indicate the
                              characters have an attribute.
          
          Practice: Turn Abbreviations off (021) and Explore your screens a
                              while and see how each of these commands affects the
                              output for your device.  When you are ready, reset all the
                              commands   Do this by entering "021", "022", "027".  You
                              could also do this by entering keypad 2 once and then enter
                              the 3 keys for the settings. i.e. "0212700".  This sequence
                              will set all the commands back and return you to layer 0.
          
          Summary:  In this lesson you have learned to:
          
                    Announce the keypad (0)
          
                    Switch to a new keypad (0#)
          
                    Turn Abbreviations on and off (021)
          
                    Turn braille Attribute Display on and off (022)
          
                    Turn speech Attributes on and off (027).
          
          
                    Lesson 6: Reading a Dialog Box
          
          Reading dialog boxes is very similiar to what you have already been doing
          when you navigate with the Explore keys.  However, there are more
          elements that you can control in dialog boxes.  In this lesson, we will
          navigate a common dialog box.  We will use a combination of Windows
          keyboard commands and ScreenPower navigation commands.
          
          Setup:    Press Alt-Tab to switch to Write.  Then press Alt-F, O to
                              bring up the Open Dialog Box.
          
                    What you should read:    EB 1 N File Name: *.wri
          
                    What you should hear:    Dialog Box Open Edit Box N File
                                                       Name: *.wri
          
                    What's happening?
          
                    Whenever you open a dialog box, ScreenPower tells you
                              that it is opening a dialog box and the name of the dialog
                              box.  In this case it said "Dialog Box Open," because this is
                              the Open Dialog box from the File Menu in Write.  After
                              Windows opens a new window or dialog box, ScreenPower
                              jumps to the focus and announces it or shows it on the
                              braille display.
          
          Step 1:   Press the Tab key to move from one item to the next in the
                              dialog box.  Stop when you get back to the File Name Edit
                              Box
          
                    What you should read?    Each element in the Dialog Box.
          
                    What you should hear?    Each element in the Dialog Box
          
                    What's happening?
          
                    Each time you press the Tab key, Windows moves the focus
                              to the next control in the Dialog Box.  ScreenPower
                              announces each one as you move to it. For most controls
                              this may be enough information, i.e. the OK and Cancel
                              buttons.  But some controls, like the List Boxes may require
                              some exploration.
          
          Step 2:   Be sure you are on the File Name Edit box.  Type the name
                              of the directory where you installed your ScreenPower for
                              Windows files and press Enter.  This is usually C:\SPWIN.
          
                    What you should read:    EB 1 N File Name: *.wri
          
                    What you should hear:    Edit Box N File Name: wri
          
                    What's happening?
          
                    By typing the directory you want to look at, Write switched to
                              the new directory and listed all the files that had a WRI
                              extension.  However, the file we are looking for has a TXT
                              extension so we need to change the file type Write is looking
                              for.
          
          Step 3:   Press the Explore Out key (4) once.
          
                    What you should read:    DB Open
          
                    What you should hear:    Open Dialog Box
          
                    What's happening?
          
                    By Exploring Out one level, you are at the top of the Open
                              Dialog Box.  From here you can Explore In to look at each of
                              the elements in the dialog box.
          
          Step 4:   Press the Explore In key (6).
          
                    What you should read:    Info Open: TB LAB B2 EB LB2
                                                       DLB2
          
                    What you should hear:    Info Title Bar, Label, Button 2,
                                                       Edit Box, List Box 2 Drop Down
                                                       List Box
          
                    What's happening?
          
                    The Info Line is giving you a quick list of all the controls in
                              the Dialog Box.  Let's say we want to retrieve the
                              README.TXT file for ScreenPower.
          
          Step 5:   Press the Explore Down key (2) until you get to the first
                              Dropdown List Box.
          
                    What you should read:    DLB 1 T List Files of Type: Write
                                                       Files (*.WRI)
          
                    What you should hear:    T List Files of Type: Write Files
                                                       (*.WRI) Dropdown List Box
          
                    What's happening?
          
                    ScreenPower is telling you the name of the Dropdown List
                              Box and the current setting.
          
          Step 6:   Press the Explore In key (6).
          
                    What you should read:    No change on display, computer
                                                       beeps.
          
                    What you should hear:    No speech output, computer
                                                       beeps
          
                    What's happening?
          
                    All the information about this element has been presented
                              and ScreenPower has no more information to give. 
                              However, we know that this is a type of List Box and there
                              should be a list of choices.  However, Dropdown List Boxes
                              only show the current setting.  To see more settings you
                              need to click on this control.
          
          Step 7:   Click the Mouse key (5) once.
          
                    What you should read:    LBI 1 Write Files (*.WRI)
          
                    What you should hear:    Write Files (*.WRI) List Box Item
                                                       1.
          
                    What's happening?
          
                    When you clicked on the Dropdown List Box, it caused the
                              list of items to drop down and moved the focus to the
                              currently selected item.  Though you can use Explore
                              commands to read the list, often not all list items are shown
                              in the dropdown box..  Explore commands typically can only
                              read items that are shown in the Dropdown Box.  To read
                              the items most effectively, lets use some Windows keys.
          
          Step 8:   Press the Down Arrow key on the cursor pad (not the
                              number pad).

                    What's happening?
          
                    The focus has moved to a new setting for the List Files of
                              Type List Box. 
          
          Step 9:   Press Down Arrow until you get to the Text Files entry. 
                              Then, press Enter on the alphanumeric keyboard (not the
                              number pad).
          
                    What you should read:    DLB 3 T List Files of Type: Write

                                                       (*.TXT) Dropdown List Box
          
                    What's happening?
          
                    The Focus has moved back to the main Dropdown List Box
                              element and ScreenPower is announcing the new List Files
                              of Type setting you chose.  Now lets Explore to find the
                              README.TXT file.
          
          Step 10:  Press the Explore Up key (8) until you get to the first List
                              Box.
          
                    What you should read:    LB 1 readme.txt
          
                    What you should hear:    readme.txt List Box One
          
                    What's happening?
          
                    ScreenPower is telling you that you have reached a list box
                              and the first item in that list box is README.TXT.  Since we
                              are looking for a list of file names, and the first item looks
                              like a filename we are probably in the right place.
          
          Step 11:  Press the Explore In key (6).
          
                    What you should read:    Info readme.txt: VSB LB2
          
                    What you should hear:    Info: Vertical Scroll Bar List Box
                                                       Item 2
          
                    What's happening?
          
                    ScreenPower is telling us that this List Box contains a
                              vertical scroll bar and 2 items.  Later we will look at how to
                              use scroll bars.  For now, lets look at the list box items.
          
          Step 12:  Press the Explore Down key (2) until you get to
                              README.TXT.
          
                    What you should read:    LBI 1 readme.txt
          
                    What you should hear:    readme.txt
          
                    What's happening?
          
                    You have navigated to the readme.txt filename.
          
          Step 13:  Double click the mouse key (5).
          
                    Note: Some keyboards have trouble with the double key
                              click.  If you have trouble, click the mouse key once and
                              then press Enter on the alphanumeric keyboard.  Do not
                              press Enter on the number pad.
          
                    Braille Users Tip You can also perform a mouse click from
                              your braille display.  PowerBraille users can click or double
                              click the concave key on the front panel.  System 90 users
                              can press Display Buttons 4 and 6.  Note: Its often easier to
                              double click from the keypad than from the braille display
                              panel keys.
          
                    What you should read:    B 1 C Convert (D)
          
                    What you should hear:    Dialog Box Write C Convert
                                                       Button default..
          
                    What's happening?
          
                    Since we changed the type of file we are loading from
                              Write's default to a text file, we are getting a dialog box that
                              is asking us to if we want to convert the document.
          
                    Braille Users Tip You could use the Explore commands to
                              read this dialog box to find out more about what it says.
          
                    Speech Users Tip There is a special Read Window
                              command on layer 8 which tells you the contents of the
                              window.  Press 08 and then the Plus key on the number
                              pad.  Remember to switch back to layer 0 (00) when you are
                              done listening to the dialog box.
          
          Step 14:  Press Enter on the alphanumeric keyboard (not on the
                              number pad).
          
                    What you should read:    The first line of the document.
          
                    What you should hear:    The first line of the document.
          
                    What's happening?
          
                    Since the Convert Button was the default setting for this
                              dialog box, pressing Enter told windows to accept the default
                              and convert the document.  The document was then loaded
                                                            and ScreenPower read the first line of text.  Lesson 7:  Working With Text
          
          This lesson is broken into two separate sections, one presenting
          commands for working with a braille display and the other with using
          speech functions.  In this lesson you will learn how to read and edit text
          using both ScreenPower and Windows commands.
          
          When you are working with large text blocks, such as those found when
          you are using a word processing program, ScreenPower for Windows
          allows you to read text much as you would normally.  As you move the
          cursor through the document, ScreenPower follows it with both speech
          and braille.
          
          
Working With Text Braille Functions
          
          In order to complete this lesson, you should be using a PowerBraille 40,
          David, INKA or DM80.  If you are using another supported display, see
          Appendix F for a list of how the front panel keys perform.
          
          Setup:    You should have the ScreenPower for Windows
                              README.TXT file open in Write (see Lesson 6).
          
                    Your display should be on the first line of text.
          
          Step 1:   Press the Scroll Display Forward key (9).
          
                    What you should read:    The next 40 characters of the
                                                       text.
          
                    What's happening?
          
                    The Scroll Display Forward and Back keys move you
                              through the text, just as they would in a DOS screen.  The
                              next step shows you how to route the cursor when you find
                              an error or get to a place you want to edit.
          
          Step 2:   Press the Touch Sensor above the character where you
                              want to move the cursor.  Then Click the mouse once. 
                              Remember you can click the mouse with the (5) key on the
                              number pad or the concave key on the front of the power
                              braille.
          
                    What you should read:    The cursor under the selected
                                                       character.
          
                    Note for Navigator 40 users Navigator 40 does not have a
                              Touch Sensor strip.  You can bring the cursor to the last
                              word on the line by pressing the mouse click key.
          
          
Working With Text-Speech Functions
          
          Setup:    You should have the ScreenPower for Windows
                              README.TXT file open in Write (see Lesson 6).
          
                    Your cursor should be on the first character of the text.  If it
                              is not, press Ctrl-Home to move the cursor to the top of the
                              document.
          
          Step 1:   Press the Explore Down key (2).
          
                    What you should hear:    The next line of text.
          
                    What's happening?
          
                    ScreenPower treats each line of text as a separate element,
                              allowing you to Explore Up and Down through the text a line
                              at a time.  However, if you want to review text on the screen
                              without moving the cursor, you can use several
                              ScreenPower functions to accomplish this.
          
          Step2:    Switch to Keypad 8 (08).
          
                    What you should hear:    Layer 8 Speech
          
                    What's happening?
          
                    You have activated the Speech Review Layer.  There are
                              commands on this layer for reading text by characters, word,
                              line and window.
          
                    This layer provides speech commands for reading the
                              previous, current and next unit in a triplet arrangement.  The
                              key to the left in the triplet reads the previous unit, the key in
                              the middle of the triplet reads the current unit and the key to
                              the right of the triplet reads the next unit.
          
                    To review text by character, use the 1, 2 and 3 keys.  If you
                              press the 2 key a second time, ScreenPower announces a
                              word that begins with the character.  
          
                    To review text by word, use the 4, 5, and 6 keys.
          
                    To review text by line, use the 7, 8, and 9 keys.
          
                    To review the window, press the Plus key.
          
          Practice: Practice the above commands by reading through the text in
                              the window.  Remember, these commands do not move
                              past the window boundaries.  If you want to bring more text
                              on the screen, press Page Down.  In the next step, we will
                              look at how to bring the cursor to the point of review so you
                              can begin editing.
          
          Step 3:   Make sure keypad 8 is active (08) and press the Read Next
                              Line key (9).  At any point while the text is reading, press the
                              Mouse Click key on keypad 8 (the Delete key).
          
                    What you should hear:    The character the cursor stops
                                                       on.
          
                    What's happening?
               
                    While you are reading text, the mouse pointer is following
                              along with each word.  When you hear a place where you
                              want to put the cursor, press the mouse key.  This causes
                              Windows to move the cursor to the place where you clicked
                              the mouse.
          
          
          
          
          
          
                              Lesson 8:  Using Scroll Bars
          
          While we've been navigating the various screens in Windows,
          occasionally we've run across scroll bars.  There are two types of scroll
          bars, vertical and horizontal.  The most common is vertical scroll bars,
          though you'll also see horizontal scroll bars regularly.  Scroll bars are used
          to indicate that there is more information than can be displayed in the
          current window.
          
          Scroll bars are a very visual control in Windows.  They consist of long
          bars that run the length or width of the window with arrows pointing out at
          each end.  In the scroll bar is a small box that moves from one end of the
          bar to the other as you move through the information.  The bar represents
          the total amount of information, say the length of a document, and the box
          visually represents how far into the document you are.
          
          One way to move to a point further in the document is to move the mouse
          over the scroll bar box and drag it to another point in the bar and release
          the mouse.  The application will move to that point in the document and
          display the new information.
          
          Since this is very difficult to do if you cannot see the screen, ScreenPower
          has a special way to manipulate scroll bars.  This lesson will show you
          how to use scroll bars.
          
          Setup:    From the Write document you are currently in,  switch to
                              layer 0 (00), then explore out two times.
          
                    What you should read:    W! 1 Write Document (and the
                                                       first line of text)
          
                    What you should hear:    Window Write Document (and
                                                       the first line of text)
          
          Step 1:   Press the Explore Down key (2)
          
                    What you should read:    VSB 0% [-----------------------------]
          
                    What you should hear:    Vertical Scroll Bar 0 Percent
          
                    ScreenPower tells you that you have encountered a scroll
                              bar and the relative position of the scroll box.  In this case it
                              is at the very top of the bar (at 0% of the entire bar).  Now
                              let's move the scroll bar.
          
                    Braille Users Tip ScreenPower also shows a braille
                              representation of the scroll bar with a row of dashes
                              between brackets.
          
                    The next step shows you how to move the scroll box.
          
          
          Step 2:   Press the Scroll Bar Dialog Box key (033).  Remember, 033
                              means switch to layer 3 and press the "3" key.
          
                    What you should read:    0
          
                    What you should hear:    Layer 3 Utilities Dialog Box Set
                                                       Scroll Position 0.
          
                    What's happening?
          
                    This is a ScreenPower dialog box that lets you set how far
                              (as a percentage) you should move the scroll box.  Let's say
                              you want to move halfway through the document.  
          
          Step 3:   Type "50" on the alphanumeric keyboard and press Enter.
          
                    What you should read:    VSB 50% [-----------------------------]
          
                    What you should hear:    Vertical Scroll Bar 50 Percent
          
                    What's happening?
          
                    ScreenPower has automatically moved the scroll box about
                              halfway through the document.  Sometimes the number
                              announced is not exactly the same as you entered. 
                              Windows is not always able to go to the exact percentage
                              specified, but will try to get as close as it can.
          
                    Navigate back to the text.  Do not press a cursor movement
                              key to jump back to your text.  Windows does not move your
                              cursor when you use a scroll bar, it only moves to show the
                              new text in the window.  If you press a cursor movement
                              key, Windows jumps back to where the cursor is (back at the
                              beginning of your document).  If you want to bring the cursor
                              to the new text, just perform a mouse click in any of the new
                                                            text.Lesson 9: Naming Windows
          
          ScreenPower gives you the capability to assign your own name to any
          window that appears in the navigation tree.  This often aids in navigation
          since you are able to describe a window in terms that make the most
          sense to you.
          
          We have already named a lot of windows in the applications that are
          provided with Windows.  However, you can change those names if you
          like.
          
          In this lesson, we will navigate to a window that is already named and
          change the name.
          
          Setup:    Make sure you are in a document in Write.
          
                    Press the Explore Out key (4) twice.  Then press the Explore
                              Down key (2) twice.
          
                    What you should read:    WI 2 Status Bar  Page #
          
                    What you should hear:    Window Status Bar Page #
          
                    What's happening?
          
                    You have navigated to the Status Bar window and it is
                              showing you the current page number of your document. 
                              Now let's rename it.
          
          Step 1:   Press the Name Window key (045).  Remember, 045 means
                              change to layer 4 and press the "5" key.
          
                    What you should read:    Status Bar
          
                    What you should hear:    Status Bar
          
                    What's happening?
          
                    ScreenPower has displayed the Name Window Dialog Box
                              and is telling you the current name of the window.  If you
                              were on a window that had not been named already,
                              ScreenPower would have only announced the dialog box.
          
          Step 2:   Type a new name for the window.  Use "Status Line".  When
                              you are done, press Enter.  If you make a mistake, use the
                              Backspace key to correct.
          
                    What you should read:    WI 2 Status Line Page #
          
                    What you should hear:    Window Status Line Page #
          
                    What's happening?
          
                    ScreenPower has changed the name of the window and is
                              announcing the new name.  You may want to repeat the
                              above steps and set the name back to Status Bar.
          
          
          
          
          
          
                    Lesson 10:  Naming Bitmaps
          
          ScreenPower also lets you name Bitmaps in a similar manner to naming
          windows.  Bitmaps are pictures on the screen that represent items or
          actions.  For example, in the Program Manger, each item in a group also
          has a picture attached to it.  In some word processors there are special
          function bars that have a row of pictures, each picture or bitmap,
          representing an action such as save or print.
          
          In this lesson, we will learn how to give a name to any bitmap we
          encounter.
          
          Setup:    Hold the Alt key down and press the Tab key until Windows
                              indicates that you are switching to the Program Manager,
                              then let up on the Alt key.  Remember, when we do this we
                              are not closing Write.  We are only switching away from it.
          
                    When you are back in the Program Manager, press Alt-W to
                              open the Window Menu, then press the Down Arrow key
                              until you are at Main.  Then press Enter.
          
                    Alternately, you can use the Navigation commands you have
                              learned earlier to explore to the Main Group.
          
                    When you get to the Main Group, use the Left, Right, Up or
                              Down keys to move to the File Manager Item.  You could
                              also use exploration commands.  When File Manager is
                              selected, press Enter.
          
                    What you should read:    LBI ##  [Open Folder] spwin
          
                    What you should hear:    [Open Folder] spwin List Box
                                                       Item ##
          
                    Note:  The actual name of the bitmap and list box item may
                              differ on your system.
          
                    What's happening?
          
                    ScreenPower is announcing the focus in File Manager. 
                              ScreenPower uses a convention that shows bitmap in
                              brackets to indicate that the element contains a bitmap. 
          
                    Note: In some predefined applications such as Microsoft
                              Word, bitmaps with no text associated with them do not use
                              brackets.
          
                    The brackets are purely a convention used when naming
                              bitmaps.  If you do not want to use brackets, you are not
                              required to and ScreenPower does not add them.  Now lets
                              rename this bitmap.
          
          Step 1:   Enter the Name Bitmap Dialog box (044).  Remember, 044
                              means change to layer 4 and press the "4" key.
          
                    What you should read:    [Open Folder]
          
                    What you should hear:    [Open Folder]
          
                    What's happening?
          
                    ScreenPower is showing you the current name of the
                              bitmap.  If no bitmap name is assigned, ScreenPower
                              announces the dialog box only. Now let's rename the
                              bitmap.
          
          Step 2.   Enter the new bitmap name.  Use "[Parent Folder]" for this
                              lesson.  Then press Enter.
          
                    What you should read:    LBI # [Parent Folder] spwin
          
                    What you should hear:    [Parent Folder] spwin List Box
                                                       Item ##
          
                    What's happening?
          
                    The new name Parent Folder has been assigned to the
                              bitmap.  Now repeat steps 1 and 2 to rename the bitmap
                              back to [Open Folder].
          
          Summary   In this lesson you learned that when ever you encounter a
                              bitmap, you can assign your own name to that bitmap using
                              the Name Bitmap command (044).
          
          
          
                              Lesson 11:  Search the Tree
          
          Because of the way ScreenPower collects information about what is going
          on in your Windows environment, you can search for any text string that
          you have encountered, including bitmap and window names
          
          In this lesson we will perform two searches, one to find the window we
          named previously and then we will search for the bitmap you named in
          File Manager.
          
          Setup:    None Required.  In the next steps we will assign a search
                              string, then search for that string.
          
          Step 1:   Press the Search String Dialog Box command (012). 
                              Remember, 012 means switch to layer 1 and press the "2"
                              key.
          
                    What you should read:    DLB 1
          
                    What you should hear:    Dropdown List Box.
          
                    What's happening?
          
                    This is the Search String Dialog Box.  This is where you
                              enter the string you want to look for.
          
          Step 2:   Type Status Bar and press Enter.
          
                    What you should read:    Your previous element
          
                    What you should hear:    Your previous element.
          
                    What's happening?
          
                    After you enter the search string, you are returned to the
                              place where you called the dialog box.  Now lets perform the
                              search.
          
          Step 3:   Press the Explore Out key (4) until you are at the Desktop. 
                              Then press the Search Down Tree command (013) then 00
                              to switch back to layer 0.
          
                    What you should read:    WI 2 Status Bar
          
                    What you should hear:    Window Status Bar
          
                    What's happening?
          
                    ScreenPower has searched the tree and found the first
                              occurrence of Status Bar.  There may be other occurrences
                              in the tree and if you repeat the search command you will
                              find them.  
          
                    ScreenPower does not require you to start the search from
                              the Desktop.  We did it in this case to make it easier.  You
                              can search Up or Down the tree from where you are but it is
                              not always apparent which is the best way to go.  By starting
                              at the Desktop, you will always search down the tree.  As
                              you use ScreenPower more, you will begin to get a sense of
                              what direction you would search to find what you are looking
                              for.
          
                    Once you have found the correct element, you can use the
                              Explore commands to navigate the area and review what's
                              there.
          
                    Now let's repeat these steps and search for the bitmap we
                              named earlier
          
          Practice: Press the Explore Out key (4) until you are at the Desktop. 
                              Press 012 to enter the search string.  Type [open folder] (if
                              you used a different name, use it instead) and press Enter. 
                              Then use the Search Down command (013) to find the
                              bitmap.
          
                    Note:  The search command is not case sensitive, so you
                              can use lower case for your searches.  Also, even though
                              ScreenPower maintains as much information as possible,
                              some items that you have encountered before may not be in
                              the tree when you perform the search.  If ScreenPower can
                              not find the search string, you will hear a beep.
          
          
                    Lesson 12: Reading the On-Line Manual
          
          Windows provides an on-line help system that can be called as a
          separate application.  We have provided the ScreenPower for Windows
          manual as a Windows help file that can be called at any time while using
          ScreenPower.
          
          Note: It is possible that calling the On-line Manual will move your focus
          away from where you where working.  When you exit the on-line manual
          you may not be where you thought you where.   This happens if the focus
          is changed or Windows was not sure where the focus was when you
          called the on-line manual.
          
          Setup:    None Required
          
          Step 1:   Press 00, Plus (switch to layer 0 and press the plus key).
          
                    What you should read:    WI # ScreenPower For Windows
                                                       Help
          
                    What you should hear:    Window ScreenPower For
                                                       Windows Help
          
                    What's happening?
          
                    Windows help files do not use a cursor, so the focus of a
                              help file is always the main window.  Now you can explore
                              this just as you would any other window.
          
          Step 2:   Press the Explore In key (6).
          
                    What you should read:    Info ScreenPower For Windows
                                                       Help: TB MB WI3
          
                    What you should hear:    Info Title Bar Menu Bar Window
                                                       3
          
                    What's happening?
          
                    All Windows help files use this same format with a title bar,
                              menu bar and two or three windows.  The title bar and menu
                              bar work very much like title bars and menu bars you have
                              looked at earlier.  If you would like, take some time to
                              explore them.
          
                    Window 1 contains several buttons for controlling the help
                              file. These buttons let you search the help file, back up or
                              move forward from topic to topic, etc.   If you would like to
                              learn more about these buttons, you should read the help
                              screens activated by the How To Use Help menu item from
                              the Help menu.  
          
                    Not all help screens have the second window.  If they do, it
                              usually contains the title of the help screen.
          
                    The last window contains the actual help information.  
          
          Step 3:   Explore Down (2) to the last window.  Explore In (6) then
                              Down, then In again and Down again.
          
                    What you should read:    The first line of the help text.
          
                    What you should hear:    The first line of the help text.
          
                    What's happening?
          
                    The above commands are the standard way to explore any
                              window.  You should understand from earlier lessons what is
                              happening when you give these commands 
          
                    Now you can use the Explore Down key (2) to read through
                              the text item.  You may want to turn on Attribute Display for
                              speech (027) or braille (022) since topic headings are shown
                              in different attributes.  When you read a topic you are
                              interested in, click the mouse key to activate the help screen
                              about that topic. (Note: when you switch help screens, the
                              old one is no longer available in the tree.  If you want to back
                              up, you need to go to the first window and click on the Back
                              Button.)
          
                    After you have a new help screen, ScreenPower is not
                              always at the top of the text.  Press the Jump to Info Line
                              key to get to the top and use the Explore Down key to read
                              the text.
          
                    When you are done reading the help file, press the Alt-F4
                              key to close the help program.
          
          
Lesson 13:  Playing Minesweeper
          
          Minesweeper is a graphical program provided with Windows.  Due to the
          complex graphical layout of the program, it is recommended that you have
          a braille display with a Touch Sensor strip for this program.  The
          instructions below assume you are using such a braille display.
          
          Setup:    Make sure you are in the Program Manager.  Navigate to the
                              Games Group and open the Minesweeper program.  Think
                              of all the steps as a test of what you have learned earlier in
                              these lessons and Minesweeper is your reward for learning
                              them
          
          Step 1:   Explore to the Minesweeper Client Area. (Explore In, Down,
                              Down, Down, In.
          
          Step 2:   Explore Down several times in the Client area to the first row
                              of bitmaps.  These bitmaps are defined already to be a row
                              of brackets and periods.  Note:  There are several blank
                              lines before you get to the bitmaps.  Note:  If you are using
                              speech, you may want to turn it off (08, Minus).
          
          Rules:    The goal of Minesweeper is to identify all the bombs hidden
                              on the screen without blowing up any.  The screen consists
                              of 8 rows of 8 blocks, each hiding a bomb or an open space. 
                              When you click on a block (shown by [.]) you uncover the
                              space under it.  If there is a bomb, you lose.  
          
                    If there is no bomb, you will get a number.  This number tells
                              you how many bombs are in the 8 blocks surrounding the
                              block you are on (3 blocks above, 3 blocks below and one
                              on either side).  If there are no bombs in the surrounding
                              spaces, no number 0 is shown and Minesweeper clears
                              space up to the next bombs.
          
                    If you suspect a bomb is under a block, you can mark it with
                              a flag by clicking the right mouse button key.  The goal is to
                              find all the bombs (10 in the beginner level).
          
                    Now lets play a game.
          
          Step 3:   Put your keypad onto layer 5 (05).
          
          Step 4:   Press a Touch Sensor above any of the characters on the
                              display.  This puts the mouse on the block you select.  You
                              can press any of the three sensors above the symbols for
                              each block ([.]).  Then click the mouse button on the braille
                              display.  Your display should update and show you either a
                              number or a bomb.  If you get a bomb, you lose.
          
                    If you lose, press F2 to start a new game.
          
                    If you see a number, that means the blocks surrounding the
                              space with the number have that many bombs in them.  For
                              example, you may have a number 3 with 5 blocks still
                              covered.  This means 3 of the 5 blocks have bombs in them. 
                              Your job is to deduce which ones have bombs.
          
                    If you suspect a block is a bomb mark it by clicking the right
                              mouse button.  Do this with the Click Right Mouse Button
                              command on layer 5 (key 6).  You can also perform a Left
                              Mouse Click from this layer with key 4.
          
                    Tip Explore up and down with the braille display panel keys
                              so you don't have to keep switching layers.  Place your
                              finger on a single block and explore up and down to find out
                              what symbols are located in the blocks surrounding your
                              selected block.
          
                    Good Luck!

Chapter 8: Utility Programs This chapter describes how to use several
utility programs provided with ScreenPower for Windows.Chapter 1:  Basic Navigation Commands
          
          The navigation commands in ScreenPower's exploration mode provide a
          powerful set of tools for exploring and interacting with Windows screens. 
          ScreenPower for Windows maintains an internal image of the screen in
          which all items are organized into groups and sub-groups according to a
          hierarchical, tree-like structure.  This image is called the "navigation tree."
          The navigation commands allow you to explore and work with the items in
          this structure. 
          
          Keypad layer 0 contains all exploration mode navigation commands.  This
          is the default layer and should be selected at all times during normal
          operation.  To select this layer, press the "0" key on the number pad twice
          in rapid succession.  In this section, when we list a command it is given
          with the keypad prefix.  If a given layer is active, you only need to enter
          the last key.  However, it does not hurt to enter the full three key
          command.  This assures you are on the right pad.
          
          
Braille Display Keys
          
          Most of the keys and key combinations available on the different braille
          displays supported by ScreenPower for Windows have been defined to
          issue one of the navigation commands described below.  These keys are
          not affected when alternative keypad layers are selected and thus offer a
          way to explore the screen at any time, even if keypad layer 0 is not active. 
          
          Since several displays with different key layouts are supported, see
          Appendix F for a complete list of supported braille displays and the
          functions assigned to each of the front panel keys.
          
          
Information Format
          
          ScreenPower for Windows provides a great deal of information about
          each item it encounters.  This information is announced and displayed in
          a specific order.  The user may adjust many output attributes to suit
          personal preferences, but the basic format of this information is not
          changed.
          
          The following categories of information are always provided in braille.  To
          make speech more effective, some items are not spoken and the order
          may change.  For example, when you encounter a command button,
          speech switches the order and announces the name of the button and
          then the fact that it is a button. 
          
          Item Type This is the general classification of the item, i.e. Window,
          Dialog Box, Command Button, etc.  However, the braille user may choose
          to have the entire name or an abbreviation displayed.  Speech output for
          the item name is always expanded. (For a complete list of the
          abbreviations used in ScreenPower for Windows, see Appendix E.)
          
          Relative List Number This information is available in braille only. Since
          each item encountered is part of the navigation tree, it belongs to a group
          of items at a particular level.  The items in the group are counted and
          summarized on the Information Line for the group.  That is, the items in a
          window might be summarized as "Group Box 5, Command Button 2."  To
          help you maintain a sense of orientation while exploring these items,
          ScreenPower for Windows assigns a number to each item in this group
          according to a specified sort order.  This number is purely informational
          and can be eliminated.
          
          Short-Cut key If a short-cut key is available for the item, this character
          is displayed and spoken immediately before the item's name.
          
          Item Name The item's name or the text displayed with this item is then
          presented.  If the item is a combined element, the assigned bitmap name
          or the words "[BM?]" are also displayed.  If the item is highlighted or
          selected, the braille display will indicate this information by adding dots 7
          and 8 to each character.  Speech can be set to indicate the selected
          items.
          
          Status Screen highlights are often used to indicate the current status of
          an item to a sighted user.  ScreenPower for Windows announces and
          displays this information.  The status information is announced for speech
          users and displayed in parentheses on the braille display.  The braille user
          can choose to have the status information displayed in words or
          abbreviations.  Some common status modes are:
          
               Set (S) Indicates this item is currently selected.
          
               Default (D) Indicates this is the default option or selection.
          
               Checked (C) Indicates a check box has been set to the "Yes" or
                         "On" status. 
          
               Dimmed (Dim) Indicates this item cannot be used or selected in
                         the current situation.  
          
               Has Dialog box (DB) Indicates that selecting this item will open a
                         dialog box of options.
          
               Has Submenu (SM) Indicates that selecting this item will open a
                         new menu of options.
          
           
Navigation Arrow Keys
          
          The four arrow keys on the number pad, (numbers "2", "4", "6", and "8"),
          can be used to move through the navigation tree.  These keys allow you
          to move from level to level of the tree or permit you to examine the items
          at a particular level.  The mouse pointer is pulled along to each item
          encountered while exploring with these keys.
          
Explore In and Out
          
          Commands: 004, 006
          
          The right and left arrow keys allow you to move from one level to another
          in the navigation tree.  The right arrow (6) is called the "Explore In" key
          and is used to move one level deeper into the tree along the current
          branch.  The left arrow (4) moves "Explore Out" one level towards the
          desktop which is the root of the tree.  The "Explore In" key provides
          access to the sub-elements of the current item.  The "Explore Out" key
          moves to the parent element of the current item.
          
          When you press the "Explore In" key, ScreenPower displays and
          announces an Information Line which describes the items at the new
          level.  This line identifies the types of objects ScreenPower encounters
          and summarizes this information for quick reference.  For example, if you
          encounter a window while exploring the screen and request more
          information by pressing the "Explore In" key, you might see the following
          Information Line on the braille display:
          
               Info:  Sample Application TB MB WI2 IC5
          
          When you are using speech, abbreviations are automatically expanded. 
          The above info line would be announced as
          
               Info: Title Bar, Menu Bar, Window 2, Icon 5
          
          This indicates that the window contains a title bar, a menu bar, two
          sub-windows, and five icons.  The abbreviations may be replaced by the
          complete words depending on the status of the Abbreviation Toggle.  For
          a complete list of the names and abbreviations used for Windows objects
          in the ScreenPower for Windows program, refer to Appendix E. 
          
          When you press the "Explore Out" key, you simply move one level up the
          navigation tree towards the desktop.  This does not close or affect the
          sub-element you moved away from in any way.  It merely returns you to
          the parent element which contains the sub-element.  Thus, if you pressed
          the "Explore Out" key while reading the above Information Line,
          ScreenPower might present a line such as:
          
               WI 3: Sample Application
          
          This would tell you that the Sample Application window described earlier
          is one of at least three windows open in a larger window.
          
          When it is not possible to Explore In or Out any further on that level, the
          computer beeps.
          
Explore Up and Down
          
          Commands: 002, 008
          
          The "Explore Up" and "Explore Down" arrow keys allow you to move to
          the next or previous item in the group at the current level.  When you
          move "Explore In" the navigation tree and obtain an Information Line, you
          are at the top of a list which identifies each item summarized on this line. 
          For example, if you obtained the Information Line discussed above, you
          could use the "Explore Down" key to examine each item on the
          Information Line.  That is, the first time you press the "Explore Down" key
          the title bar would be displayed and announced.  The next press of the
          "Explore Down" key would move the exploration focus to the menu bar of
          the window, and so on.
          
          While the exploration focus is on any one of these items, pressing the
          "Explore In" key would provide a descriptive Information Line for that item. 
          Using these functions, a visually impaired user can obtain a precise
          picture of the "functional" layout of a Windows screen.  Since the mouse
          pointer follows the exploration focus, it is always possible to interact with
          any item encountered.  ScreenPower's "informational" mode of operation
          is not the physical layout of items on the screen.  It provides an easy and
          efficient way to use complex screens, even when some elements are not
          visible.
          
          When it is not possible to Explore Up or Down any more on the same line,
          the computer beeps.
          
          
Jump to Information Line
          
          Command: 001
          
          Although you can always move to the Information Line for the current
          group of items by using the navigation arrow keys, ScreenPower for
          Windows provides a more efficient way to move the exploration focus
          directly to this information.  Pressing the "1" key in keypad layer 0
          announces and moves the braille display directly to the current
          Information line.  If you become disoriented or simply wish to move to the
          top of the current item list, this command can be very helpful.
          
          The information displayed on an Information Line is always presented
          according to the following format:
          
          Info The word "Info:" is placed at the left margin to indicate a
          ScreenPower Information Line.
          
          Item Name The name of the current item is announced and displayed
          along with its group or parent window name if applicable.
          
          Sub-Element List The sub-elements for this item are summarized and
          listed in the order they will appear in the navigation tree.  Please note the
          order they are listed in the tree may be different than their placement on
          the screen.
          
          If an Information Line is obtained for a client area which contains only text
          and an insertion point, the number of static lines and the relative row and
          column position of the insertion point will be displayed.
          
          
Path Display Key
          
          Command: 003
          
          While you are learning to use Windows or getting acquainted with new
          application programs, you may sometimes become disoriented and lose
          track of your exact position in the navigation tree.  If this happens, you can
          ask ScreenPower for assistance by pressing the "3" key in keypad layer 0.
          
          Since ScreenPower constantly updates the navigation tree each time a
          change occurs on the screen, the program is always aware of your exact
          location in this information structure.  Whether you are using focus
          tracking or exploring the screen with the navigation keys, ScreenPower
          can always provide the path from your current position to the root of the
          tree.
          
          When you press the "3" key, this path is spoken and displayed in braille. 
          To clear the path information, simply press the "3" key a second time.
          
          ScreenPower for Windows's path information is presented in a specific
          format.  Since the current object or group is the most significant piece of
          information, the name of this item is listed first.  This name is followed by
          a backslash, then the name of the parent object which contains the
          current item is listed.  This pattern is repeated until you reach the desktop
          which is the root of the navigation tree.  For example, if you are currently
          in the "Write" application window which is located in the "Accessories"
          group in the Program Manager window, your path might be:
          
               Write\Program Manager - Group Accessories\WI 1 Program           Manager\Desktop
          
          By listing the items in this order, ScreenPower allows you to stop reading
          the path information as soon as you obtain enough information to reorient
          yourself in the navigation tree.  
          
          
Scroll Braille Display Back and Forward
          
          Commands: 007, 009
          
          While using the navigation keys to explore or read text on the screen, you
          will probably encounter lines which are too long to be displayed on a 20-
          or 40-cell braille display.  To move the display forward, press the "9" key
          in keypad layer 0.  This will advance to the next 20 or 40 character
          positions.  If this action causes the braille display to move to a new line,
          the entire line will be spoken when using speech output.  To move the
          display backwards or left 20 or 40 character positions, press the "7" key.
          
          
Mouse Click
          
          Command: 005
          
          The "5" key in keypad layer 0 offers an alternative way to issue mouse
          button commands.  When you navigate to an item and "click" this key, you
          move the focus and "select" that item.  When you "double click" the "5"
          key by pressing and releasing it twice in rapid succession, you expand an
          icon or perform an action defined by your application.  This command
          allows you to take advantage of the simplicity and convenience offered by
          mouse functions. 
          
          Note:  If an item is already selected, clicking on this item can de-select it. 
          This can occur when you use a horizontal menu bar which provides a
          pull-down menu for each item.  In this case, the item in the horizontal bar
          is already selected as soon as you move the focus or navigate to this
          item.  Clicking on this item rather than pressing the Down arrow to open
          the pull-down menu will close the entire menu bar.
          
          
Jump to Focus
          
          Command: 00, Delete
          
          When you are exploring a group of Windows items such as a series of
          command buttons, one of the items in the group will already be selected. 
          That is, the Windows focus will already be on a specific item.  On the
          braille display, this item will be highlighted by adding dots 7 and 8 to each
          character in its name.  Also, the item's name will be followed by the letter
          "S" or "D" in parentheses which indicates that this option is selected.  The
          speech will announce the item's name then say "Set" or "Default".  
          
          When you move to a group of items using the navigation keys, you may
          be placed on the selected item automatically.  However, if you move away
          from this item during further screen exploration, ScreenPower provides a
          way to quickly move back to the highlighted item.
          
          Pressing the "DELETE" key in keypad layer 0 will always move the
          exploration focus to this item.  Thus, this key offers a way to quickly
          identify the current "focus" of the Windows operating system.  
          
          
Execute Short-Cut Keys
          
          Command: 00, Enter
          
          When a Windows item can be selected or activated using a short-cut key,
          a character in the item's name is underlined on the screen.  ScreenPower
          informs a visually impaired Windows user of this option by displaying and
          announcing the short-cut key character immediately before the name of
          the item.  
          
          To use a short-cut key, you would typically press the indicated character
          either alone or in combination with the Alt key.  However, since it is not
          always convenient to move your hand away from the navigation keys to
          enter this command, ScreenPower provides an alternative method.  
          
          When a short-cut key is available, you can issue the short-cut command
          simply by pressing the Enter key on the number pad.  This issues the
          short-cut command whether or not the Alt key was expected.
          
          
On-Line Manual
          
          Command: 00, Plus
          
          This command calls a standard Windows help file containing the contents
          of this manual.  The manual may be called at any time using this
          command.  See lesson 12 in Part 3: Using ScreenPower for Windows for
          instructions about reading the on-line manual.
          
          Note:  When you close the on-line manual (Alt-F4) you may not return to
          the same point you were at originally.  Since Windows is multitasking
          while you are in the manual, the focus may shift to another point.
          
Select/Announce Keypad Layers
          
          Command: 0#
          
          All ScreenPower for Windows commands and options can be activated
          from the number pad.  This significantly reduces the risk of keyboard
          conflicts and allows the user to work efficiently.  However, since many
          more options are available than can be assigned to the 17 keys available,
          a series of 10 layers or keypad overlays has been developed.  
          
          Each keypad layer serves as a sub-menu for a group of commands. 
          When a new layer is selected, each key is assigned a new function. 
          Thus, the "2" key may initiate a string search in keypad layer 1 and speak
          the current character in layer 8.  In this way, more than 100 different
          commands and options can be assigned to the number pad.  
          
          To select a keypad layer, press the "0" key on the number pad followed by
          the number key for the desired overlay.  For example, to change to the
          speech command layer, you would press and release the "0" key, then
          quickly press the "8" key.  Once you are in a new layer each of the keys
          on the number pad would then initiate a specific speech output function
          until a new layer is selected.
          
          If you are using speech, the synthesizer announces the name of the
          keypad layer.  If you are not sure which layer is active, press the 0 key by
          itself.  After a short pause, ScreenPower announces the current active
          layer.  Braille does not provide any indication of keypad layer changes.
          
          Keypad layer 0 is the default layer and contains the navigation commands
          described above.  To return to layer 0, simply press the "0" key twice in
          rapid succession.
          
          NOTE:  When you press the "0" key to indicate you wish to switch to a
          new keypad layer, you must press the layer number within a very brief
          period of time.  If you hesitate before pressing the second key, the current
          layer will be announced.  You must then press the "0" key again before
          selecting the new layer number.  
          
          
                              Chapter 2:  Speech Commands and Options
          
          This chapter discusses commands specifically related to speech
          commands and options.
          
          
The Silence Keys (Shift or Control)
          
          Pressing the Control or Shift key while ScreenPower is speaking will
          instantly silence speech.  Note: Avoid using the Alt key to silence the
          speech.  Windows uses the Alt key to activate the menu in an application. 
          If this happens, just press the Alt key again to turn the menus off.
          
          
Screen Review Commands
          
          Layer 8 contains screen review commands which allow a speech user to
          carefully examine the screen.  These screen review commands are limited
          to the Windows element currently at the focus.
          
Reading Characters
          
          Commands: 081, 082, 083
          
          The "1", "2", and "3" keys read the previous, current, and next characters
          respectively.  These functions are restricted to the current line.  If you
          have trouble understanding the pronunciation of the character, press the
          "2" key twice in rapid succession to announce a word which begins with
          the current character.
          
Reading Words
          
          Command: 084, 085, 086
          
          The "4", "5", and "6" keys in layer 8 speak the previous, current, and next
          words respectively.  These commands are restricted to the current line.
          
Reading Lines
          
          Command: 087, 088, 089
          
          The "7", "8", and "9" keys in layer 8 read the previous, current, and next
          lines respectively.  The speech cursor is moved into the line spoken.
          
          
Mouse Click
          
          Command: 08, Del
          
          The Delete key in keypad layer 8 offers an alternative way to issue mouse
          button commands.  This command functions the same as the mouse click
          on keypad 0, key 5.  When you navigate to an item and "click" this key,
          you move the focus and "select" that item.  When you "double click" the
          Delete key by pressing and releasing it twice in rapid succession, you
          expand an icon or perform an action defined by your application.  This
          command allows you to take advantage of the simplicity and convenience
          offered by mouse functions. 
          
          Note:  If an item is already selected, clicking on this item can de-select it. 
          This can occur when you use a horizontal menu bar which provides a
          pull-down menu for each item.  In this case, the item in the horizontal bar
          is already selected as soon as you move the focus or navigate to this
          item.  Clicking on this item rather than pressing the Down arrow to open
          the pull-down menu will close the entire menu bar.
          
          
Read Window
          
          Command: 08, Plus
          
          This command reads the entire contents of the current window or dialog
          box.  Use this command to get an overview of any window or dialog box.
          
          
Read Down Current Level
          
          Command: 08, Enter
          
          This command reads down the current level from the current point.  Use
          this command to hear the contents of the current level when you are on
          the Info Line.
          
          
Speech On/Off
          
          Command: 08, Minus
          
          This command turns the speech on and off.
          
          
The Speech Options Dialog Box
          
          Command: 048
          
          Pressing the "8" key in keypad layer 4 opens the Speech options dialog
          box.  This window contains several option buttons and check boxes which
          allow the user to customize speech output.
          
          Though you can use Windows commands such as Tab, Shift-Tab and the
          arrow keys to use this dialog box, it is best to use ScreenPower Explore
          commands to best access this dialog box.
          
          Some options are not available in the first release of ScreenPower for
          Windows.  These options will be dimmed in the dialog box.
          
Capital Letters
          
          The Capital Letters group box contains several option buttons which allow
          the user to specify how capital letters will be spoken.  The options are:
          
          Ignore Select Ignore if you do not want Screen Power to notify you of
          capital letters.  Select any of the other options if you want Screen Power
          to notify you of capital letters.
          
          Say If you select Say, Screen Power says the word "cap."  If the whole
          word is capitalized, it says "all cap."
          
          Pitch If you select Pitch, Screen Power speaks the capital letter in a
          higher pitch.
          
          Tone If you select Tone, Screen Power beeps, or sounds a tone for
          capital letters.  If the whole word is capitalized, you will hear a double tone
          preceding the word.
          
          Volume If you select Volume, ScreenPower says capital letters in a
          louder volume than the rest of the text.
          
Blank or Space
          
          The blank or space option controls how ScreenPower for Windows
          announces blank areas and spaces between characters.
          
          Ignore Select Ignore if you do not want Screen Power to notify you of
          blank spaces.  Select any of the other options if you want Screen Power
          to notify you of blank spaces.
          
          Say If you select Say, Screen Power will say the word "space".
          
          Click  if you select Click, Screen Power will cause your computer to
          issue an audible click (not all synthesizers can do this).
          
          Pause if you select Pause, Screen Power will pause at each space.  
          
          All If you select All, Screen Power will tell you all spaces it encounters (if
          it encounters four spaces, it says "four spaces"). 
          
Punctuation
          
          The punctuation option controls how ScreenPower pronounces
          punctuation.
          
          Repeat Dialog Box Use the Repeat Punctuation Options to tell Screen
          Power how to handle repeated punctuation symbols, such as three
          asterisks in a row.  You can have Screen Power say repeated punctuation
          once, twice, three times, four times, or tell you how many of them there
          are. 
          
          Ignore Select Ignore to have Screen Power pronounce no punctuation.
          
          Some Select Some to have Screen Power pronounce everything but
          periods, question marks, exclamation marks, colons, semi-colons, single
          quotes, left and right parentheses, left and right brackets, and left and
          right braces.
          
          Most Select Most to have Screen Power pronounce everything but
          periods, question marks, and exclamation marks.
          
          All The default is All.  With this setting, all punctuation is pronounced.
          
          Pause Check Box Use Pause Options to tell Screen Power whether to
          pause at punctuation or not.  
                  
Voice Settings
          
          The Voice Settings option controls how ScreenPower sounds.  These
          options functions may work better with certain synthesizers.
          
          Rate Use this option to set the speaking rate for the speech synthesizer. 
          The higher the number the faster the speaking rate.
          
          Volume Use this option to set the volume of the speech synthesizer. 
          The higher the number, the higher the volume.
          
          Pitch Use this option to set the pitch of the speech synthesizer.  The
          higher the number, the higher the pitch.
          
          Voice Use this option to change the sound of the voice used by your
          speech synthesizer.  The effects of this option vary among different
          synthesizers.
          
Numbers
          
          The numbers option determines the way in which numbers are spoken
          when text is read.  The default is to say numbers as Digits.
          
          Digit Choose Digit if you want Screen Power to pronounce a four-digit
          number, such as "1234," as "one two three four." 
          
          Full Use Full mode to separate a series of numbers that has (for
          example) commas between each number. Full mode applies to any
          number series with separators such as decimal points, commas, or
          dashes.
          
          Pair  Choose Pair if you want Screen Power to say "twelve thirty-four." 
          This mode is most useful for pronouncing dates. 
          
          Word  Word mode will include the commas as part of the number.
            
          Full and Word are rather similar.  Use Full mode to separate a series of
          numbers that has (for example) commas between each number.  Word
          mode will include the commas as part of the number. Full mode applies to
          any number series with separators such as decimal points, commas, or
          dashes.  Their differences are best illustrated in examples with decimal
          points or commas.  Decimal points and commas can be used either as
          parts of one number or as a means to separate a series of numbers.  
          
          The number 1,234 (with a comma) in Word mode is pronounced as "one
          thousand two hundred thirty four."  You would not use Full mode to say
          this number because Full mode would make the number into a series of
          two numbers separated by a comma.  The first number would be the
          number 1.  The second number would be the number 234.  Therefore, in
          Full mode 1,234 would be spoken as "one comma two hundred thirty
          four."  
          
          If you have several numbers, such as a list of test scores or temperatures,
          separated by commas, such as 100,95,58,83,89, you should use Full
          mode.  In Full mode, this series will be spoken as "one hundred comma
          ninety five comma fifty eight comma eighty three comma eighty nine." 
          Word mode would try to make sense of this as one number, with limited
          success depending on the actual numbers in the series.  
          
          Use Word mode if you have a number that includes a decimal point, such
          as 123.45.  Word mode pronounces this number as "one hundred twenty
          three point four five," which is traditionally correct.  Full mode would try to
          make the number into a series of two numbers separated by the period as
          a delimiter.  Therefore, the number would be pronounced "one hundred
          twenty three period forty five."  
          
Text
          This option controls how the speech announces text that is being
          reviewed.
          
          Word This option sets ScreenPower to read text word by word.
          
          Spell This option sets ScreenPower to spell all text.
          
          Say and Spell This option sets ScreenPower to say each word then
          spell it.
          
Miscellaneous Options
          
          These options control several miscellaneous speech functions
          
          Say Single Quotes Check this option if you want single quotes
          pronounced as text is read.  Uncheck this option if you do not want to hear
          single quotes.
          
          Use Dictionary This option is not available in the current release of
          ScreenPower for Windows.  ScreenPower for DOS users can set up
          dictionary entries in the DOS program and they will used by ScreenPower
          for Windows.
          
          Expand Abbreviations This option is not available in the current
          release of ScreenPower for Windows.  ScreenPower for DOS users can
          turn on the Use Abbreviations function in the DOS program and they will
          used by ScreenPower for Windows.
                    
          
                    Chapter 3:  Auxiliary Functions
          
          Keypads 1, 2 and 3 provide auxiliary functions and utilities to improve your
          use of ScreenPower for Windows.  Each function is described below in
          the order in which it appear on the keypad.
          
          
Search Functions
          
          Commands: 011, 012, 013
          
          Screen Power for Windows provides a powerful search function which can
          move the focus to any item in the navigation tree.  This allows the user to
          quickly move to and launch an application even if its icon is not currently
          displayed on the screen.  
          
          To initiate a search, press the "2" key in keypad layer 1. At this point, you
          should type the name of the item for which you are searching.  You may
          enter the entire name or any unique portion of the name.  Although capital
          letters will be accepted, the search function is not case sensitive.  Use the
          "Backspace" key to correct any errors while typing.
          
          Press the Enter key on the alphanumeric keyboard  to indicate the search
          string is complete.  You must now choose whether the item is deeper in
          the navigation tree than your current position or closer to the root of the
          tree.  Press the "3" key to move downward or deeper into the tree during
          the search.  Press the "1" key to search upwards towards the root of the
          navigation tree.
          
          Note: Searches are only successful if the item you are looking for is
          available in the tree.  For example, if you minimize an application to an
          icon, none of the information from that application is available to the tree
          and the Search function will not find it.
          
          If the search is successful, the focus will be placed on the item found. 
          The usual descriptive information will be announced and displayed just as
          if you had navigated to this item.  If you want to know your current position
          in the navigation tree, return to the navigation layer by pressing "0" twice
          in rapid succession, then press the "3" key to display the current path.  
          
          
          
Update the Tree
          
          Command: 014
          
          Although Screen Power for Windows always tries to update the navigation
          tree as soon as any screen change is detected, some applications may
          occasionally confuse this process.  If this occurs, items which are on the
          screen may not be in the navigation tree or an item which was removed
          from the active screen may still be in the navigation tree.  In this case, the
          navigation tree needs to be updated in order to synchronize exploration
          functions with Windows actions.
          
          To instruct Screen Power to update the navigation tree at any time, simply
          press the "4" key in keypad layer 1.  
          
          
Move to Mouse Pointer
          
          Command: 015
          
          This function moves the navigation focus to the element where the mouse
          pointer is currently located.  This function can be helpful for both a visually
          impaired Windows user and a sighted instructor.
          
          While teaching Windows concepts and applications, a sighted teacher
          could use the actual mouse to provide screen orientation information. 
          Pressing the "5" key after moving the mouse would identify the item at the
          new location.
          
          
Attribute Information Dialog Box
          
          Command: 016
          
          This function provides information about the location and appearance of
          the item or text being displayed or spoken.  A list box containing the
          following information appears:
          
          1.   The name of the element at the focus or the text is displayed.
          
          2.   The coordinates of the screen area which contains the item or text
                         are listed.  The word "Rect" is displayed and spoken followed by
                         the pixel location of the top, left, right, and bottom edges of the
                         rectangle.  For example, "Rect L 10 T 17 R 220 B 76" describes a
                         small rectangular area near the top, left corner of the screen.
          
          3.   The font type and size is given for each character in the block of
                         text.
          
          Use the navigation keys in layer 0 to review the information in this dialog
          box.  Press the Esc key to clear this information and return to your
          application.
          
          
Typing Output Mode
          
          Command: 017
          
          This option sets the speech output options for text entered as you type.  
          These are different from the output options set in the Speech Settings
          Dialog box.  The three options are:
          
          1.   Typing Output Off No speech output is used as you type text.
          
          2.   Character Mode Each character is announced as you type text.
          
          3.   Word Mode Each word is announced as you type text.
          
          
Typing Override On/Off
          
          Command: 018
          
          This option toggles between typing override on and off.  When typing
          override is off, each word or character you type is spoken.  When typing
          override is on, each new word or character interrupts the output of the
          previous word or character.  With typing override on, it is possible to type
          fast enough that you will not hear complete words or characters spoken
          until you pause.  With typing override off, you will hear every character or
          word entered no matter how fast you type.
          
          
Abbreviations On/Off
          
          Command: 021
          
          When using a braille display with ScreenPower for Windows, the type of
          element being used is always identified at the left edge of the display.  For
          example, if you are currently examining an icon, the word "Icon" might
          appear at the left edge of the display.
          
          ScreenPower can display this information in two different forms.  In the
          long form, the element type is displayed using full words.  In the short
          form, an abbreviation is used.  Thus, a window may be identified as
          "Window" or "WI".  Pressing the "1" key in layer 2 toggles between the
          short and long form display.
          
          Note: This option affects braille output only.  Speech output always uses
          the expanded form.
          
          
Attributes Display On/Off
          
          Command: 022
          
          Windows uses a wide variety of screen and text highlighting techniques to
          provide extra information to the user.  Some of this highlighting
          information is presented to the visually impaired Windows user in
          descriptive words.  However, dots 7 and 8 on the braille display can be
          used to indicate some screen attributes.  For example, when reading a list
          of option buttons in braille, the currently selected button is indicated by
          adding dots 7 and 8 to each character.
          
          While this braille highlighting technique is generally very helpful, there
          may be times when the extra dots interfere with efficient reading.  This
          can be especially true when reading numbers and unfamiliar
          abbreviations.  If you would prefer to temporarily disable dots 7 and 8,
          simply press the "2" key in keypad layer 2.  To enable the display
          attributes once again, press the "2" key a second time.
          
          
Cursor Display
          
          Command: 024
          
          This option is not available with all braille displays and configurations. 
          When available, press key "4" on layer 2 to cycle through the available
          types of cursor presentation.   ScreenPower uses two types of cursors, a
          full cell or dots 7 and 8.
          
          
Host Window On/Off
          
          Command: 025
          
          The host window displays information about the elements in the tree just
          above and below the current item.  This option is only available as a visual
          option since it displays the same information shown on the braille display
          or announced with speech.
          
          Pressing the "5" key in keypad layer 2 alternately hides and restores the
          host window.  This allows a sighted colleague or instructor to examine the
          navigation tree to determine how best to explore to new areas of the
          screen.
          
          While the Host Window is displayed, ScreenPower for Windows can be
          closed and removed from the Windows environment.  To remove
          ScreenPower from the Windows environment, show the Host window,
          then press Alt-F4.
          
          
Speech Attributes On/Off
          
          Command: 027
          
          Use this option to announce the attributes of characters while reading with
          speech.  As ScreenPower for Windows encounters attributes such as
          italics, bold, highlighted, etc. the speech announces when the attribute is
          turned on and off in the text.  Turn this option off if you do not want to

Print Braille Image
          
          Command: 028 
          
          While learning the Windows operating system or a new application, it may
          sometimes be helpful to obtain a braille image of an element.  The BrlPrint
          utility sends a tactile representation of the element at the focus to a braille
          printer connected to your computer.  This utility is activated by pressing
          the "8" key in keypad layer 2.
          
          
Cursor Announcing On/Off
          
          Command:029
          
          This function turns on Announcing of the cursor when encountered in an
          edit box or text line.  When on, ScreenPower says "cursor" at the point
          where the cursor is located.  When off, ScreenPower ignores the cursor
          with speech.
          
          
Scroll Bar Dialog Box
          
          Command: 033
          
          ScreenPower for Windows provides a way for visually impaired Windows
          users to manipulate information on the screen through the standard scroll
          bar functions.  This allows you to move very quickly to a new position in a
          large text file and helps you to locate specific information in long lists of
          options.
          
          When a vertical or horizontal scroll bar is encountered, your relative
          position in the text or list is described as a percent of distance from the left
          or top of the scroll bar.  Thus, when you first enter a document, the scroll
          bar line would indicate "0%" distance from the top of the document.  
          
          To "scroll" to a new location, press the "3" key in layer 3.  A cursor will
          prompt you for a number which represents the percentage of distance you
          wish to move along the length of the scroll bar.  If you make a mistake
          while typing, use the Backspace key to make corrections.  Press the Enter
          key when the number is correct.  Screen Power will move to the list item
          or line which is closest to the value you entered.
          
          Windows does not move the cursor to this point.  If you try to move the
          cursor with the cursor keys, Windows will jump back to original place in
          your document.  To force the cursor to the new screen, click anywhere in
          the text.
          
          
Drag and Drop Functions 
          
          Commands: 037, 038, 039
          
          The Windows operating system allows the user to move items around on
          the screen using a mouse.  The mouse pointer is placed on the item to be
          moved, then the left mouse button is pressed and held.  The mouse
          pointer is then moved to a new location and the mouse button is released. 
          The original item is moved to or "dropped" in the new location.  This
          operation makes it very easy to perform such tasks as moving an
          application from one group to another.
          
          Screen Power for Windows provides an alternative, keyboard method to
          perform drag and drop operations.  To move an element, follow these
          steps:
          
          1.   Move the focus to the item you wish to move.  Press the "7" key in
                         keypad layer 3.  Screen Power identifies the item at the
                         corresponding pixel coordinates and stores this information as the
                         Drag Source.
          
          2.   Now move the focus to the position where you wish to move the
                         element.  Press the "8" key in layer 3 to set the Drop Location
                         coordinates.
          
          3.   Finally, press the "9" key in layer 3 to execute the drag and drop
                         operation.  Screen Power moves the mouse pointer to the source
                         item, simulates a press and hold function on the left mouse button,
                         then drags the item to its new location.  As a final step, the mouse
                         button is released and the item is "dropped" into place.  This step
                         may take a few seconds.  You could then use the Path function in
                         layer 0 to verify that the item is in its new location.
          
                              Chapter 4: Configuration and Customization
          
          This chapter describes several configuration and customization options
          available in ScreenPower for Windows.
          
          
User Setup Dialog Box
          
          Command: 042
          
          The User Setup dialog box determines how information about Windows
          elements will be presented.  Changes made in this window remain set
          throughout all Windows sessions until changed by the user.
          
Displaying Element Names
          
          The options in this group box determine how the names assigned to
          Windows elements will be displayed on the braille display.  The three
          options are:
          
          None No information is provided about the type of Windows elements
          encountered.
          
          Short Abbreviations are used to identify the type of Windows elements.
          (Default)
          
          Long Full words are used to describe Windows elements.
          
Tree Presentation Modes
          
          The navigation tree has three different levels of information presentation. 
          This option allows you to change the amount of information presented.
          
          Deep Deep mode presents all elements available in the tree.
          
          Medium Medium mode presents all elements except Multi-Document
          Windows and empty Client Areas.
          
          Flat In flat mode several related elements are grouped together. 
          (Default)
          
Setting Element Sort Order
          
          The order in which elements are presented is controlled by the sort order. 
          This setting affects the presentation order of elements on the info line and
          when navigating up and down a level.
          
          Type The elements are sorted according to their type.
          
          Ordinal The elements are sorted according to the order in which
          Windows presents them.
          
          Geographic The elements are sorted by how they appear on the
          screen, starting in the upper left corner to the lower right. (Default)
          
Group Box (Frame) Display Options
          
          This option affects how group box items are presented.  This option has
          two settings.
          
          Text The text mode presents items from group boxes on the same level. 
          This may cause elements from several group boxes to be displayed on a
          single line.
          
          Parent The Parent mode presents elements from a group box in a
          hierarchy.  Only elements from a single group box are presented on a
          level. (Default)
          
Miscellaneous Display Options
          
          These options affect the display of window class names and element
          numbers.
          
          Show Window Class Names
          
          Each window has an internal description called the window class name. 
          When this option is checked, the internal description is displayed as the
          window name when no name is assigned (See the Window Name Dialog
          Box section later in this chapter).  When this option is not selected, no
          name is displayed if a name has not been assigned.
          
          Show Element Numbers
          
          When more than one of the same type of element is presented in the
          same level, each element is numbered.  When this option is unchecked,
          element numbers are not displayed.
          
          
Bitmap Dictionary Dialog Box
          
          Command: 044
          
          Screen Power for Windows allows the user to assign a unique name to
          each bitmap pattern encountered.  These names are placed in a bitmap
          dictionary and can be changed at any time.  The assigned name is
          displayed immediately before the text label, if any, associated with the
          bitmap.  Many common icons in the Windows operating system and in
          some popular applications have been defined.  However, you will need to
          define many more.
          
          The characters "[BM?]" are displayed when a bitmap not currently in the
          dictionary is encountered.  You can frequently infer the purpose of the
          bitmap from the text label for the icon.  Also, the context-sensitive help
          system can sometimes be used to determine the purpose of the icon. 
          However, you will need sighted assistance to define many bitmaps used in
          applications.
          
          To assign a name to a bitmap, press the "4" key in keypad layer 4.  If the
          bitmap has already been defined, the current name will be displayed with
          a cursor.  To change this name, press the Backspace key to clear the
          existing characters, then type the new name.  When assigning a name,
          we have chosen to enclose the name in brackets to distinguish bitmaps
          from other text labels.  We would recommend you do the same.   If the
          bitmap has not yet been assigned a name, you will see only a cursor
          where the new name should be typed.  Correct any typing mistakes with
          the Backspace key.  
          
          When the new name is correctly typed, press the Enter key to add this
          bitmap definition to the dictionary.  The assigned name will be spoken and
          displayed each time an icon with this bitmap is encountered in any
          application.
          
          
Name Window Dialog Box
          
          Command: 045
          
          The Window Name dialog box lets you assign descriptive names to
          windows and align bitmaps that appear in a window.
          
The Name Window Edit Box
          
          Screen Power for Windows allows the user to assign a unique name to
          each window encountered.  These names can be changed at any time. 
          The assigned name is displayed immediately after the window element
          name.
          
          To assign a name to a window, press the "5" key in keypad layer 4.  If the
          window has already been named, the current name will be displayed with
          a cursor.  To change this name, press the Backspace key to clear the
          existing characters, then type the new name.  If the window has not yet
          been assigned a name, you will see only a cursor where the new name
          should be typed.  Correct any typing mistakes with the Backspace key.  
          
          When the new name is correctly typed, press the Enter key.  The
          assigned name will be spoken and displayed each time the window is
          encountered.
          
The Align Check Box
          
          The align function causes a series of bitmaps to be presented on a single
          line or as separate elements in a level.  For example, in the Minesweeper
          program, the align function is checked to cause the bitmaps to appear on
          a single line.  When this option is unchecked, each Minesweeper bitmap
          appears on a separate line in the tree.  In other client areas it separates
          the text labels from their associated bitmaps.
          
          
Speech Options Dialog Box
          
          Command: 048
          
          This function controls speech settings.  For more information, see chapter
          2 of this section.
          
                    Chapter 5:  Mouse Functions
          
          
Mouse Control Functions
          
          These functions are all assigned to layer 5.  These functions allow you
          simulate certain types of mouse functions that may be required for
          specialized applications.
          
Press Mouse Button
          
          Commands: 051, 052, 053
          
          These keys simulate pressing and holding a mouse button down.  Key 1
          simulates the left button, key 2 simulates the middle button, key 3
          simulates the right button.
          
          After you have pressed one of these keys, switch to layer 0, navigate to
          where you need to release the mouse, switch back to layer 5 and use
          keys 7, 8, or 9 to release the mouse.
          
Click Mouse Button
          
          Commands: 054, 055, 056
          
          These keys simulate clicking a mouse button.  Key 1 simulates the left
          button, key 2 simulates the middle button, key 3 simulates the right button. 
          To simulate a double click, repeat the last key twice quickly. This function
          is slightly different from the 05 command.  When executed, this command
          clicks where the mouse really is on the screen.  The 05 mouse command
          clicks where you expect the mouse to be.  Often these are the same
          place.
          
Release Mouse Button
          
          Commands: 057, 058, 059
          
          These keys simulate releasing a mouse button.  Key 1 simulates the left
          button, key 2 simulates the middle button, key 3 simulates the right button.
          
          Press on of these keys to release a key you have held down using keys 1,
          2, or 3.
          
          
          
                    Chapter 6: Monitor Window Options
          
          Screen Power for Windows can place a "monitor" window on the screen
          which contains the information being spoken and displayed in braille.  This
          monitor window can be very helpful for a sighted assistant or teacher, and
          is helpful for low vision users.  
          
          A variety of display options is available for the Monitor window.  Once
          these options have been set, they are active in each of your Windows
          sessions until changed.
          
          
Show/Hide Monitor Window
          
          Commands: 061, 063
          
          To turn on the monitor window, press the "1" key in keypad layer 6.  This
          is useful for sighted colleagues or instructors to visually show what   
          appears on the braille display.
          
          When the Monitor Window is turned on, it may partially or completely hide
          other information on the screen.  If this happens, the window can be
          "hidden" by pressing the "3" key in keypad layer 6.
          
          
Move Monitor Window
          
          Commands: 062, 064, 066, 068
          
          When the monitor window is shown, the four arrow keys in keypad layer 6,
          (2, 4, 6, and 8), can be used to move it to a new position on the screen. 
          Simply press the arrow key which corresponds to the direction in which
          you wish to move the window.
          
          
Increase/Decrease Monitor Window Font Size
          
          Commands: 067, 069
          
          The "7" and "9" keys in keypad layer 6 can be used respectively to
          decrease and increase the font size in the monitor window.  Each time
          one of these keys is pressed, the font size is altered by a very small
          increment.  The size of the monitor window also changes, obscuring or
          covering more or less information on the screen.
          
Monitor Setup Dialog Box
          
          Command: 065
          
          A dialog box appears in which you can set the font, font style (bold, italics,
          etc.), font size, and font color.
                    Chapter 7: Bookmark Functions
          
          The Bookmark functions allow you to place a marker in the navigation
          tree.  Later you can jump back to any bookmark that is available in the
          tree.
          
          
Set New Bookmark
          
          Command: 071
          
          Use this command to enter a new bookmark.  The Set Bookmark Dialog
          Box allows you to enter the name you want to assign to the bookmark. 
          Use the Backspace key to edit the name if you make a mistake.
          
          
Select Bookmark
          
          Command: 072
          
          Use this command to select a bookmark which has already been entered.
          A dialog box appears in which a list of all defined bookmarks is presented. 
          Select the desired bookmark and close the dialog box.  Now enter the
          Jump to Bookmark command (073) to jump to the selected bookmark.
          
          
Jump to Bookmark
          
          Command: 073
          
          Use this command to jump to the selected bookmark. If the selected
          bookmark is not available in the tree ScreenPower beeps.
                                        Chapter 8: Utility Programs
          
          
          Three utility programs are provided with ScreenPower for Windows,
          metronome, a Braille print program and a program which allows you to
          work with Excel, EXTW.  
          
          
Metronome 
          
          This program indicates with a ticking sound that the user program is
          currently working and cannot accept input.  It corresponds with the hour
          glass graphic which appears on the screen.
          
          To use this program simply run it.  This can be accomplished in several 
          ways.  If you want it to automatically start it every time you use Windows,
          you can enter it in the SPWIN.INI file.  Under the [extras] section (at the
          very bottom) enter the following line:
          
               metronom.exe= 
          
          You can also start the program from within Windows from the File
          Manager or by using the "Run" command from the Program Manager
          (enter C:\SPWIN\METRONOM.EXE on the command line.  Or you could
          define a program item for the program and could then run it by clicking on
          its icon.  Consult your Windows manual for more information on these
          options.
          
          
Braille Print Program
          
          The Braille print program allows you to print an image with Braille dots 
          of the current element displayed on the Braille display.  This is intended to
          help you form a picture of the elements as they appear on the screen.  
          
          First make sure you have a Braille printer (VersaPoint or Everest)
          connected and turned on.  When the program is running simply enter the
          028 command from the number pad and the current element will be
          printed.
          
          To select the printer you are using, edit the BR_PRINT.INI file in the
          SPWIN directory.  To use the VersaPoint braille printer edit the DEVICE=
          line to say:
          
               device=versa
          
          To use the Everest braille printer edit the DEVICE= line to say:
          
               device=index
          
          As with the metronome program there are several options to run the 
          program.  If you want it to automatically start it every time you use 
          Windows, you can enter it in the SPWIN.INI file.  Under the [extras]
          section (at the very bottom) enter the following line:
          
               br_print.exe= 
          
          You can start the program from within Windows from the File Manager or
          by using the "Run" command from the Program Manager (enter
          C:\SPWIN\BR_PRINT.EXE on the command line).  Or you could define a
          program item for the program and could then run it by clicking on its icon. 
          Consult your Windows manual for more information on these options.
          
          
Working with Excel
          
          The EXTW program is provided to enable you to work with Excel.  The
          Excel program uses an active cell rather than a cursor which the
          ScreenPower program cannot follow.  The EXTW places an "internal"
          cursor into the active cell which allows ScreenPower to follow it.  This
          program should be running whenever the Excel program is used.
          
          If you use Excel exclusively, then you could enter the program call in the 
          SPWIN.INI file under the [extras] section as follows:
          
               extw.exe= 
          
          If you do not use Excel exclusively, we recommend only calling the
          program before working in Excel and then closing it after you leave Excel
          because the EXTW program requires memory and processing time which
          could lead to performance degradation when working in other
          applications.
          
          Use the "Run" command of the Program Manager (enter
          C:\SPWIN\EXTW.EXE on the command line) or call the program from the
          File Manager.  Consult your Windows manual for more information on
                    these options.Appendices

          Group Box Group Boxes are usually a group of similar controls grouped
          together in box surrounded by a frame of lines on the screen.  The most
          common type of controls to find in Group Boxes are options buttons and

          Scroll Bars a horizontal or vertical bar which can appear along the
          bottom or right edge of a window.  Its purpose is to provide access to
          information not currently displayed within the boundaries of the window.  A
          second type of scroll bar can appear in dialog boxes to allow the user to
          set a variable option along a sliding scale.
          
          Short-Cut Keys a keyboard command which opens a menu or selects
          an object.  Available short-cut keys are indicated by an underlined
          character in the item's name.  While within an open window or menu, the
          short-cut key command can be issued simply by typing the appropriate
          character.  Otherwise, the short-cut character must be pressed in
          conjunction with the Alt key.
          
          Text Usually text is the information entered in a window, such as the text

Appendix F: Using Braille Displays
          
          ScreenPower for Windows supports most TeleSensory braille displays. 
          These include PowerBraille 40, David, INKA, DM80, Navigator 80 and
          Navigator 40.  This section provides information about using each of these
          displays.
          
          
Using Sensor Switches
          
          The optical sensors on David, INKA and DM80 and touch sensors on the
          PowerBraille and Navigator models, can serve three different functions in
          ScreenPower for Windows
          
          Marking text To mark text with the sensor switches, first make sure that
          the OS function is activated.  (See below for the "OS on" command for
          your braille display.  The PowerBraille sensor switches are always active).
          
          Starting from the left, move your finger over the optical sensors to the
          starting character of the text you want to mark and enter 051 from the
          number pad.  Now continue moving your finger to the last character you
          want to mark and enter 057 from the number pad.  The selected text is
          now marked.  For PowerBraille you would press the corresponding sensor
          switches of the start and end characters rather than moving your finger
          over the optical sensors.
          
          Menu routing This function can be activated when an info line for a
          menu bar is displayed.  In this case to select a menu option you can touch
          the sensor in front of the corresponding short cut key or in front of the
          element name.  
          
          Option Button Selection You can use the sensor switches to select an
          Option Button in a flat mode group.  When all the option buttons in a
          group are displayed on a single line, press or touch the optical sensor (or
          sensor switch) in front of that button.
          
          
Attribute Representation
          
          The ScreenPower for Windows representation of attributes is the same for
          all compatible refreshable braille displays:
