PARC 5-key Chord Keyboard
Bill Buxton's NotesThis five-button chord keyboard was modeled on the keyboard developed by Doug Engelbart. It was fitted to the first Xerox Alto computers, and following Engelbart, was operated by the non-mouse hand. This keyboard needs to be augmented by the three mouse buttons in order to type the full alphanumeric character set.
