Abstract

A computer, electronic, or other keyboard includes a backspace/erase key positioned such that it enables comfortable activation of the backspace/erase function via thumb movement. Such activation can be accomplished more easily, more efficiently, and more ergonomically effectively than on prior art keyboards because it can be done without averting the eyes from the text copy and does not entail moving or uncomfortable stretching of the hands.
