Abstract: A keyboard and method for inputting graphical indicium representations of language characters formed from one or a combination of character units. The keyboard includes a plurality of keys, each key having at least one unit associated therewith but with selected keys, at least, having two or more units associated therewith. Included also is a key mapping for each key whereby selection of a key generates a mapped value of a unit associated with the selected key, the mapped value having a relational correlation with one or more relevant characters. The keys are so arranged on the keyboard that visually similar units are associated with the same or adjacent keys, and units which usually form left, right, top or bottom character parts are associated with keys generally located in physically similarly related positions on the left, right, top and bottom, respectively, of the keyboard.
