A technique is described whereby cursor controls, as used to point to a cursor location on a CRT screen, are incorporated into a conventional keyboard, so as to provide combined functional capability of direct positional control, either rectilinear or diagonal. The concept is an improvement over mouse-type devices, which require desk space be used in the maneuvering of the mouse and are difficult to move in purely horizontal or vertical lines. Typically, cursor controls require the user to move at least one hand away from the keyboard typing position to reach them. The cursor movement generally has a fixed rate of speed, which is often slower than the user desires. Also, in positioning the cursor, the user will often overshoot or undershoot the target.
