1. In a data processing system having at least two input detectors, a method that permits a user, using the fingers of a single hand, to produce defined outputs, such as generating characters and executing commands, comprising: (a) generating a first single output with single activation of any one of the input detectors; (b) generating a second single output with sequential activation of any two of the input detectors based on first timing conditions; and (c) generating a third single output and a fourth single output with sequential activation of any two of the input detectors based on second timing conditions.
