A reduced size and split keyboard arrangement is provided for a portable computing apparatus. The arrangement of the keys, together with mapping of multiple characters to the keys allows reduction of the keyboard to a smaller footprint of a handheld device. Keys may have a single character or multiple characters mapped thereto. For the keys with multiple character mapping, the selection of the character may be by done by simultaneous or near-simultaneous pressing of adjacent physical keys. In one embodiment, disambiguation software may be employed to determine selection of a character from a physical or virtual key with multiple characters assigned thereto.
