KEYBOARD ENTRY SYSTEM ABSTRACT A keyboard entry system is disclosed which com- prises a keyboard which includes a plurality of letter keys, one for each letter of a selected language. The entry system responds to conventional sequential acti- vation of individual keys by providing output signals indicative of the respective individual letters asso- ciated with the activated keys to an application program such as a word processor or printer control program. The keyboard entry system also responds to chords of simultaneously activated multiple keys by using these chords to retrieve stored words from a dictionary. It is the stored words rather than the entered chords which are applied as inputs to the application program. This system allows an operator to use both conventional se- quential key entry techniques and chorded entry tech- niques for rapid data entry.
