The present invention provides a multifunctional input device. The input device includes a functional mode which defines the mode of operation of the input device. Each functional mode includes one or more domain levels with each domain level containing one or more domain-level values. Each domain level-value within each functional mode is assigned to one of a plurality of programmable input keys. The domain-level value assigned to each programmable input key controls the function of that programmable input key within a given functionality and domain level. The present invention also includes a display to indicate the domain-level value associated with each of the programmable input keys within a given functionality.
