A handheld wireless communication device includes features that make it easier to differentiate among various keys and to correctly select a desired key. It also includes features that make the device more comfortable to use. In particular, corner keys have decreasing height profiles to make above-adjacent keys easier to reach and distinguish. Additionally, lowermost, outermost portions of the corner keys may be somewhat truncated. Flanking keys in a navigation row slant toward and are flush with peripheral edges of a navigation tool assembly and have outer edges that are higher than inner edges of adjacent outer keys. The outer edges of the flanking keys may be hump- shaped or crowned. The longitudinally central portion of the device is narrower than the ends of the device, and the comers of the device are contoured to enhance comfort in a user's hand. Soft-touch materials are employed in hand-contacting portions of the device.
