A user interface for a hand held electronic device, such as a cell phone, provides multiple touch sensate feature functions. In one embodiment, the user interface may include a plurality of touch sensitive keys arranged contiguously with an outermost first subset of the plurality of touch sensitive keys symmetrically forming four corners of a substantially rectangular touch pad, a second subset of the keys arranged circularly within the outermost first subset of the plurality of touch sensitive keys, and a third subset of the plurality of touch sensitive keys arranged symmetrically within the second subset of the plurality of touch sensitive keys, wherein each of the plurality of touch sensitive keys is configured to receive user input to operate at least one feature associated with the hand held electronic device. Moreover, the second subset of the plurality of touch sensitive keys may comprise twelve keys and may be configured to mimic an analog clock layout, with each of the twelve keys representing corresponding telephonic dial pad digits, 1-9, 0, *, #, respectively. The touch sensitive key area may be overlayed with a display function, e.g., a LCD.
