A remote control device has A/V component select buttons corresponding to respective A/V components, and one or more depressible multifunction buttons each serving multiple functions. The particular function depends on which component select button was last depressed and/or on an operational state of the selected component. The multifunction button includes a matrix of illuminable elements that can be energized as appropriate to display a word, a phrase, or a symbol.
