ABSTRACT:
A mobile telephone includes a body, a display, and a keypad. The keypad is removably secured to the body and coupled to a processor. The keypad is depressible along a plurality of directions and can be switched between a first mode and second mode, wherein each combination of depressible direction and mode represent a unique group of alphanumeric letters. The processor includes word recognition software, such that a desired word can be determined from the sequence of groups of letters selected without having to select each individual letter.
