tits on a keyboard

(jargon)Small bumps on certain keycaps to help touch-typistsfind the home keys (ASDF and JKL;) without looking. They arenearly always on the "F" and "J" of a QWERTY and the "5" ofa numeric keypad. The Macintosh, perverse as usual, hasthem on the "D" and "K" keys.

This term is based on the vernacular American expression "asuseful as tits on a boar" (or boar-hog, bull, bullfrog, ormany other variants), meaning "not useful".
