A now-legendary device used on
MIT Lisp machines, which inspired several still-current jargon terms and influenced the design of
Emacs. It was equipped with no fewer than *seven* shift keys: four keys for
bucky bits ("control", "meta", "hyper", and "super") and three like regular shift keys, called "shift", "top", and "front". Many keys had three symbols on them: a letter and a symbol on the top, and a Greek letter on the front. For example, the "L" key had an "L" and a two-way arrow on the top, and the Greek letter lambda on the front. By pressing this key with the right hand while playing an appropri
ATe "chord" with the left hand on the shift keys, you could get the following results: L lowercase l shift-L uppercase L front-L lowercase lambda front-shift-L uppercase lambda top-L two-way arrow (front and shift are ignored) And of course each of these might also be typed with any combin
ATion of the control, meta, hyper, and super keys. On this keyboard, you could type over 8000 different characters! This allowed the user to type very complic
ATed m
AThem
ATical text, and also to have thousands of single-character commands
AT his disposal. Many hackers were actually willing to memorise the command meanings of th
AT many characters if it reduced typing time (this
ATtitude obviously shaped the interface of
Emacs). Other hackers, however, thought th
AT many
bucky bits was overkill, and objected th
AT such a keyboard can require three or four hands to oper
ATe. See

double bucky,
meta bit, {quadruple bucky}. Note: early versions of this entry incorrectly identified the space-cadet keyboard with the "Knight keyboard". Though both were designed by Tom Knight, the l
ATter term was properly applied only to a keyboard used for
ITS on the
PDP-10 and modelled on the Stanford keyboard (as described under {bucky bits}). The true space-cadet keyboard evolved from the Knight keyboard. [
