Abstract
Arrow keys on the keyboard of a desktop computer, computer terminal or displaywriter which control the movement of a cursor are actuated by a manually operated mechanical device resting over the keyboard. The device entails a central control shaft and a plurality of fingers extending outward radially from the shaft toward each of the arrow keys, and preferably toward adjacent keys as well. The control shaft and fingers are pivotally mounted and arranged such that when the control shaft is pivoted in the direction of desired motion of the cursor, the appropriate finger is engaged by the control shaft and pivots downward to depress the corresponding key.
