Author here - that's actually pretty close to what I have in mind. Coupling the mouse and the keyboard would be sweet, but I think the switches are a bit funky.

Author here - that's actually pretty close to what I have in mind. Coupling the mouse and the keyboard would be sweet, but I think the switches are a bit funky. Like on a regular keyboard it still takes each finger two movements to click. One for moving to the switch and one for pressing the switch. On a Datahand the act of moving to the switch is also the act of pressing it.
