ENTER
 -----
 Sends information to EDT for functions such as FIND and COMMAND.

 SUBS  (GOLD ENTER)
 ----
 Deletes the search string, replaces it with the contents of the PASTE buffer,
 and finds the next occurrence of the string.  To use:

     1.  Press SELECT.
     2.  Type the new text.
     3.  Press CUT.
     4.  Press FIND.
     5.  Enter the text you wish to replace.

 Each time you press SUBS, EDT makes one substitution and finds the next
 occurrence of the search string.  You can use a repeat count for multiple
 substitutions.
