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


To SEARCH  for a  string in  a text,   type it  in  the
TARGET EXPRESSION field,  and click 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 pull
   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  buffer  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.
