A keypad (110) for an electronic device (100) includes nested telephony keys (115) having both an indented edge and a protruded edge in a substantially planar surface. The keys (151, 152, 153, 154, 155, 156, 157, 158, 159, 161, 162, 163) have alphanumeric telephony labels consistent with the ISO Standard keypad. A priority routine enters a character of a first alphanumeric label when a switch under a key is held for shorter than a first toggle period, and the priority routine enters a character of a second alphanumeric label when the switch is held for longer than the first toggle period.
