Abstract

A character input device is disclosed that includes a plurality of character input keys and one or more mode-altering keys. Each character input key is associated with multiple characters. By activating only the character input keys, primary characters may be input. By activating the character input keys in conjunction with the mode-altering keys, however, various secondary, tertiary, and quaternary characters may be input. The mode-altering keys may be utilized in a temporary mode, wherein only one secondary, tertiary, or quaternary character is input. Alternately, the mode-altering keys may be utilized in a base mode, wherein a series of secondary, tertiary, or quaternary character is input.
