ABSTRACT:
A keyboard for an electronic processor comprises two separate keyboard units for operation by the left and right hands, respectively, having keys at locations corresponding to those of the left hand operated and right hand operated sides of a conventional, touch-typing keyboard. In one example, the keyboard units can be folded for packing in stacked relation for pocketability. In another example, the keypads are concave with the keys extending along an arc of travel of the user's fingers and a palm supporting handrest is located adjacent the keypad. Both the keys and the handrest are adjustable to accommodate hands of different sizes.
