A system and method for receiving character entries in mobile computer devices uses an improved keypad. The keypad uses a dual key press method in which each key of the keypad includes a unique key definition when it alone is pressed. Each of two adjacent keys of the keypad also include a unique key definition when the two adjacent keys are pressed at substantially the same time. A keypad controller receives inputs from the keys and decodes the single key entries and the dual key entries. The keypad occupies a relatively small keypad area while providing full size keys for the user. The keypad also has a mode key that enables a user to change the alphabet mode of the keypad to a numerical mode.
