Keyboard improvements
Abstract:
A keypad has both hill keys (12) that provide a corresponding output when individually pressed, and valley keys (14) are labeled to correspond with an output that results at least from the simultaneous or near-simultaneous manipulation of a predetermined set of two or more hill keys (12) adjacent the valley key (14). Pairs of hill keys (12) are joined to form elongated dual keys (16) that provide a nominal effective key width (H) substantially equal to a nominal effective key width (V) of the valley keys.
