Abstract
A method for backspacing and/or backspacing/erasing on a computer, electronic, or other keyboard comprises activation of the backspacing function via thumb movement. Such activation can be accomplished more easily, more efficiently, and more ergonomically effectively than prior art methods because it can be done without averting the eyes from the text copy and does not entail moving or uncomfortable stretching of the hands.
