This computer keyboard is about one-third the size of a conventional computer keyboard, yet it retains the conventional spatial relationships among the alphabetic keys and all of the characters and functions of a standard keyboard without reducing the standard surface area for finger contact on each key or the spacing between adjacent keys. The number of keys is reduced, but each of the keys (including the mode selection keys) can execute any one of three selectable movements according to the direction in which finger pressure is applied to it. This choice of key movements determines the character or function selected by a key when it is actuated. Figs. 1 and 2 are top and side views of the finger contact surfaces of each key in the single row of twelve keys constituting the compact keyboard (Fig. 3).
