One dialog takes care of both SEARCH and REPLACE.   The
SEARCH dialog  is opened  from the  SEARCH menu  or  by
pressing ^F.


SEARCH for  a string  in a  text by  typing it  in  the
TARGET EXPRESSION  field, and  clicking on  the  SEARCH
button.  Search for the next string by selecting SEARCH
NEXT in the SEARCH menu or by pressing ^G.

When ALL is selected, all strings are marked at once.

To SEARCH  and  REPLACE  a  set  of  strings, type  the
replacement in  the SUBSTITUTE  EXPRESSION field.   Now
you can either search and replace targets one by one or
replace them all at  once; to do the  first, repeatedly
select SEARCH or  press ^G and  then select REPLACE  or
press ^H.

To REPLACE ALL targets AT ONCE, select the ALL  switch,
select SEARCH, and then select REPLACE.


** Click on the TARGET EXPRESSION field to enter a drop
   down menu allowing you to choose between four  pairs
   of target/substitute expression pairs.

** The search  and  replace  system makes  use  of  the
   cut/paste  text  block  to  store  the   replacement
   strings.



The following  OPTIONS  are available  for  search  and
replace:

   ù  Wildcards on/off.   When wildcards  are  ON, some
      characters   in   the   target   and   substitute
      expressions have a special meaning.  See below.

   ù  As word.  When this is selected, the strings  are
      only marked when they constitute a full word.

   ù  Up.  When  this switch  is selected, strings  are
      found in upward direction.

   ù  Case  sensitive.    When  this   switch  is   NOT
      selected,  strings  are  also  marked  when  they
      differ in case to the original target expression.

   ù  All Expressions.  When  this switch is  selected,
      all four  target/substitute  pairs are  used  for
      searching and replacement.



WILDCARDS are used to search for strings which are  not
literally the same, but match some general pattern with
a number  of holes.   The following  characters have  a
special  meaning   in   the   target   and   substitute
expressions when WILDCARDS are enabled:

   TARGET EXPRESSION

     ?, !   Match any character
     *, &   Match any string or zero or more characters
     [a-z]  Match any of a-z
     [^a-z] Match any character not in a-z
     ^      Match the beginning of a line
     $      Match the end of a line
     \c     Match the character c literally

     \( string \)  Marks part of the string for use  in
                   the replacement.

   SUBSTITUTE EXPRESSION

     ?   The character matched by ?
     *   The string matched by *
     !   The character matched by ! or by [a-z], [^a-z]
     &   The string matched by  & or the part  enclosed
         by \( and \).
     \c  The character c literally.
