Abstract
Systems and methods provide for graphically controlling numeric, alphanumeric or other symbol-based features on a set top box (STB) or other television receiver. A keypad image is presented on the display that includes key images corresponding to the symbol-based features. A two-dimensional input is received from the remote control that indicates one of the key images, and imagery on the display is updated in response to the received two-dimensional input.
