quadruple bucky
     
        Obsolete. 1. On an MIT {space-cadet keyboard}, use of all four
        of the shifting keys (control, meta, hyper, and super) while
        typing a character key.
     
        2. On a Stanford or MIT keyboard in {raw mode}, use of four
        shift keys while typing a fifth character, where the four
        shift keys are the control and meta keys on *both* sides of
        the keyboard.  This was very difficult to do!  One accepted
        technique was to press the left-control and left-meta keys
        with your left hand, the right-control and right-meta keys
        with your right hand, and the fifth key with your nose.
     
        Quadruple-bucky combinations were very seldom used in
        practice, because when one invented a new command one usually
        assigned it to some character that was easier to type.  If you
        want to imply that a program has ridiculously many commands or
        features, you can say something like: "Oh, the command that
        makes it spin the tapes while whistling Beethoven's Fifth
        Symphony is quadruple-bucky-cokebottle."  See {double bucky},
        {bucky bits}, {cokebottle}.
