double bucky adj.
Using both the CTRL and META keys. "The command to burn all
LEDs is double bucky F."
This term originated on the Stanford extended-ASCII keyboard,
and was later taken up by users of the space-cadet keyboard at MIT. A
typical MIT comment was that the Stanford bucky bits (control and meta shifting
keys) were nice, but there weren't enough of them; you could type
only 512 different characters on a Stanford keyboard. An obvious
way to address this was simply to add more shifting keys, and
this was eventually done; but a keyboard with that many shifting
keys is hard on touch-typists, who don't like to move their hands
away from the home position on the keyboard. It was
half-seriously suggested that the extra shifting keys be
implemented as pedals; typing on such a keyboard would be very
much like playing a full pipe organ. This idea is mentioned in a
parody of a very fine song by Jeffrey Moss called "Rubber
Duckie", which was published in "The Sesame Street Songbook"
(Simon and Schuster 1971, ISBN 0-671-21036-X). These lyrics were
written on May 27, 1978, in celebration of the Stanford
keyboard:
