ABSTRACT:
User control apparatus for a system such as a television receiver having a plurality of user controllable functions such as channel, volume, brightness, contrast, color saturation and tint, includes a plurality of individual pushbuttons for changing respective functions in a first sense, e.g., "up" and a common pushbutton for changing all of the functions in a second sense, e.g., "down". Operation of one of the individual pushbuttons selects the function to be controlled and causes the function to be increased. Thereafter, operation of the common pushbutton causes the selected function to be decreased.
