Abstract
A method and apparatus of identifying and selecting characters from among a plurality of characters. In accordance with one embodiment of the invention, a computer processor electronically enables identification of each of a plurality of characters arranged in a one-dimensional array. Each character is identified by an integer value that corresponds to the number of positions the character is offset from a reference position of the one-dimensional array. The computer processor electronically enables selection of any of the characters by receiving input resulting from activation of selection keys that specify the integer value of a character desired for selection. In one further embodiment, each selection key has an assigned integer value, and the integer value that identifies the selected character is calculated by summing the assigned integer values of each selection key activated for each instance that each selection key is activated within a selectable-length time period.
