UNDEFINE KEY

 Cancels a key definition that was done with DEFINE KEY or LEARN.  (It does
 NOT cancel definitions done by a 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:

    Command                       Purpose or effects
    ---------------------------------------------------------------------
    1.  SET KEYPAD EDT            Sets the EDT keypad, which defines PF4
                                  (among other keys).

    2.  DEFINE KEY=pf4 center     Redefines PF4 as CENTER LINE, overriding
                                  the EDT definition.

    3.  UNDEFINE KEY pf4          Cancels the definition of PF4, restoring
                                  its EDT definition (Delete Line).

 Note:  You cannot undefine a key defined as DO unless there
        is another key defined as DO.
