A handheld wireless communication device configured to be hand cradleable by an operator during text entry. A display, key field and trackball navigation tool are located on a front face of the device. At least some keys of the key field are arranged in key-columns and each of the key-columns is vertically offset from adjacent key-columns. Alphanumeric input keys include several alphabetic keys with letters arranged in a traditional (QWERTY), but non-ITU Standard E.161 telephone letter layout. A microprocessor is provided that receives operator commands from the keys and the trackball navigation tool and which affects corresponding changes to the display based on user input. At least one key of the key field is positioned adjacent to the trackball navigation tool and the at least one key has an arcuate-shaped edge conformance fitting to an arcuate-shaped boundary about the trackball navigation tool.
