    said computer storing a default button specification table describing a plurality of button touch areas and corresponding button display areas in the event a button specification table is not available;

    said button panel driver program using said default table to reconfigure said plurality of button touch areas in said touch overlay and said corresponding button display areas in said display;

    an application program stored in said computer, having an alternate button specification table describing a plurality of alternate button touch areas and corresponding alternate button display areas for selection by a user; and
