Each keypad configuration, which is presented by an optical shutter (204) that opens or closes windows or shutters that are geometrically configured as alphanumeric or device keys or symbols. Each keypad configuration, in one embodiment, is limited to those needed for the particular mode of operation of the device (100). The optical shutter (204) is a low-resolution display that presents user actuation targets to a user in a low-resolution key area. As each mode of the device changes, the corresponding keypad configuration presented changes accordingly.
