ABSTRACT:
A method for controlling cursor functions on a touch typing keyboard, comprising activation of the cursor control functions via transverse force applied comfortably by 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.
