A plurality of switches are disposed about the periphery of a display. The switches input information from a user to a controlled electronic device. By pressing down on any point of the periphery of the display, two switches disposed at the corners adjacent to the pressed side are operated. A cursor, responsively coupled to the switches, moves towards the frame side that is pressed. Alternatively, displayed text can be made to move away from the side that is pressed. Further, by pressing down simultaneously on two points disposed on opposite sides of the display, a display item that is associated with the present cursor position is selected.
