Apple has filled a patent for a mouse-keyboard hybrid. A mouse key combi? Bit weird. As Apple owns FingerWorks( a multi touch keyboard company ) they have yet to experiment with this path. FingerWorks keyboards are flat with printed keys and works like the iPad’s keyboard. They regularly fetch £800 on eBay. Place two fingers down simultaneously and you can drag the mouse pointer about, tap with three fingers and said pointer will “click”. Other gestures allow for scrolling up and down, and zooming (not by pinch, as it happens; a five-finger splay is used) along with a plethora of other shortcuts too complicated to bother learning. Looks cool but weird but its Apple so it will probably work.
