UNDEFINE KEY

  Cancels the current definition of key, if it was done with the DEFINE KEY
  or LEARN command. Does not cancel definitions done by a SET GOLD KEY, SET
  FUNCTION KEYS, or SET KEYPAD command.

  You can type the key name on the command line or let EVE prompt you to
  press the key to be undefined.

  Example:

     The following commands set the EDT keypad and then redefine KP9 as
     CENTER LINE, overriding its EDT definition. UNDEFINE KEY then cancels
     that definition, restoring its EDT definition (Append).

        Command: SET KEYPAD EDT
        Command: DEFINE KEY=kp9  center line
        Command: UNDEFINE KEY kp9

  Usage notes:

  o  In specifying key combinations, use a dash, slash, or underscore as a
     delimiter in the key name. For more information, see help on Names For
     Keys.

  o  If you do not type the key name on the command line, UNDEFINE KEY
     prompts you to press the key you want to undefine:

        Function key ............. such as F20, PF3, KP0, or ENTER
        GOLD key sequence ........ such as GOLD-A or GOLD-PF3
        Control key .............. such as CTRL/A or GOLD-CTRL/A
        Shifted function key ..... such as SHIFT/F14 (DECwindows only)
        ALT key combination ...... such as ALT/Z     (DECwindows only)
        Mouse button ............. such as M2CLICK   (DECwindows only)

     To cancel the operation, press the RETURN key or CTRL/M, which cannot
     be redefined.

  o  If the specified key was previously defined by a SET KEYPAD command,
     that previous definition is restored, if the keypad setting is still in
     effect (see example above).

  o  Learn sequences containing a key you undefined may not replay properly
     because the key is undefined or defined differently. See help on LEARN.
