jargon Small bumps on certain keycaps to help touch-typists
find the home keys (ASDF and JKL;) without looking. They are
nearly always on the "F" and "J" of a
QWERTY and the "5" of
a numeric keypad. The
Macintosh, perverse as usual, has
them on the "D" and "K" keys.
This term is based on the vernacular American expression "as
useful as tits on a boar" (or boar-hog, bull, bullfrog, or
many other variants), meaning "not useful".
