Abstract
An handheld wireless communication device that is cradleable in one hand 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. A menu key is positioned adjacent to the trackball navigation tool that upon actuation displays an available action menu on the display in dependence of the currently running application on the device.
