Abstract
When a key input acknowledging unit acknowledges user input from a valid key enabled to control a first electronic device, a light-emission control unit causes a first light-emitting unit for a first selection key to emit light. On the other hand, when the key input acknowledging unit acknowledges user input from a control key other than the valid key, the light-emission control unit causes a second light-emitting unit for a second selection key or a third light-emitting unit for a third selection key to emit light.
