Format: DEFINE KEY key-name AS 'string'

 Key-name is one of the following:

     [GOLD] [FUNCTION] number
     [GOLD] CONTROL character
     [GOLD] CONTROL "character"
     [GOLD] CONTROL 'character'
     [GOLD] DELETE
      GOLD  character
      GOLD  "character"
      GOLD  'character'

 Number refers to keypad and function keys.  CONTROL character names
 specific control keys (upper- and lowercase letters are considered
 equivalent).  A character following CONTROL is limited to @, A to Z, [,
 \, ], ^ and _.  DELETE refers to the delete key, which is not a control
 character.  Character not following CONTROL can be any keyboard key
 except 0-9, though - is not useful.  Characters !, %, ', and " must be
 enclosed in quotation marks; other characters can be.
