A wireless handheld communication device having a housing containing a display screen located above a physical keyboard. The keyboard includes a plurality of physical keys and corresponding indicia. Some of the keys are associated with alphabetic characters corresponding to a QWERTY array of letters A-Z and some are associated with numeric characters 0-9 corresponding to a telephone keypad arrangement. At least some of the keys associated with numeric characters are overlaid on the physical keys associated with alphabetic characters. A microprocessor is included that runs the device in at least a telephony mode, an email mode and at least one non-calculator based additional mode. The microprocessor displays a key-function map on the display screen indicative of enabled functions associated with particular physical keys of the keyboard which are different from any function signified by the indicia associated with the respective particular physical key.
