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.
