A computer input device similar to a "mouse" which may be embodied in a single keyboard key switch mechanism with a key cap that is displaceable within horizontal plane with one finger. Displacement of the key cap results in similar directional movement of the cursor on the computer display; greater directional force applied to the key cap results in increased velocity of movement of the cursor on the computer display.

Why it's free to use
- Filed December 11, 1989. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 11, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 11, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
