Abstract
A system and method for providing expanded functionality from a remote control handset, wherein multiple command functions are effected by the actuation of a single key or control surface. A remote control handset is programmed to recognize the actuation of keys or control surfaces associated with multiple-functionality. In response to a standard actuation (such as the momentary depression of that key) of a multiple-functionality key, a primary remote control signal is generated by the remote control handset for purposes of controlling a first remote system or component. The remote control handset is further adapted to test for and recognize a non-standard actuation (such as double-clicking or prolonged depression) of a multiple-functionality key, and responsively generate a second remote control signal. This second remote control signal can be generated for purposes of providing and alternate command to same system or component that is controlled by the primary remote control signal associated with the actuated key, or to an completely separate system or component.
