                ------- DELLAST (Function Key) -------


--  This function key deletes (or undoes) the last action taken
    (LINE, CURVE, PAINT, CIRCLE, NEW PT)

--  This may be especially helpful in undoing a PAINT operation
    that was destructive.  (See PAINT for more information.)      

--  The DELLAST function key pressed repeatedly will delete (or undo)
    the drawing (one thing at a time), proceeding backwards from
    the last thing done to the first.

    NOTE  If you wish to delete more than just the last action taken,
          see DEL10 for more information.
