Command           Description

CTRL S            These two keys when pressed together will
                  pause the present activity.  It will stop
                  screen scrolling and halt the printer.  A
                  likely use would be  to change the printer's
                  paper when jammed.  Hitting CTRL S again will
                  resume activity.

CTRL ALT DEL      These three keys when hit together will
                  "reboot" the system.  Rebooting is similar to
                  turning the machine off and back on.  This is
                  a good command to try only when the computer
                  seems hung and no input is accepted from the
                  keyboard.

SHIFT PRTSC       These two keys allows us to print whatever is
                  on the screen.  It may be useful in recording
                  error messages or displaying data not readily 
                  available on reports.  For instance printing a 
                  single master file record.

CHKDSK /F         Used to check the memory  available for use 
                  and the amount of diskspace. The /F parameter
                  is used to rebuild bad file allocations.

FORMAT            Used to ready a diskette for copying during
                  the backup procedure.

                        USEFUL Keystrokes

Cursor Movement

The cursor, a flashing minus sign, may be moved through the use
of the four directional keys on the right hand side of the
keyboard.  The upper arrow is used to return back to the
preceding field.  The down arrow or the RETURN key are used to
move on to the next field.  The right and left arrows move the
cursor one space in the corresponding direction.

      Vendor PE     
      Invoice test12     
      Date    12/31/87

For instance, if the cursor was sitting on the eight of the date
field, hitting the up arrow twice would move it to the Vendor
field.  If I wanted to move it only to the beginning of date, I
would hit the left arrow 4 times, since the "/" are fixed and not
considered part of the data.

Any field where the last character entered fills up the display,
the computer will automatically assume the entry is finished and
will continue onto the next field.  In the case of most menu
selections, therefore, hitting return after a selection is not
necessary.

Screen Function Keys

While processing data on a data screen, certain key combination
can be used to facilitate the process. Intuitively, moving the
cursor key with the arrows, as described above and pressing the
DEL and INS keys will get the job done  and may be all that is
necessary. However, there are advantages to using the keystrokes
listed below:

  CTRL A          Moves the cursor a Word to the left.
  CTRL F          Moves the cursor a Word to the right.
  CTRL Home       Moves the cursor to the top of the screen.
  CTRL END        Moves the cursor to the bottom of the screen.
  CTRL T          Deletes the word to the right of the cursor.
  CTRL Y          Deletes from the cursor position to the end of
                  the field.
  CTRL U          Restore the current field to its original
                  value, as long as you did not exit the field. 
  CTRL U          Terminate the current process, saving all
                  changes made including the current field.
  ESC             Terminate current process, saving all changes 
                  but those made to the current field.
