ABSTRACT:
The invention comprises an ergonomic means for activation of cursor control keys on a computer or electronic typewriter keyboard by utilizing transverse pressure on the cursor control keys applied via the thumbs. The cursor control keys (26, 28, 60, 62) are positioned within comfortable reach of the thumbs such that activation may be done by a touch typist without looking at the keyboard, without uncomfortable stretching, and without moving an entire hand.
