  • Keyboard and method for switching key code with a single modifier key
    Patent number: 6320519
    Abstract: A keyboard with key codes switchable by means of a single modifier key and a method of control thereof are provided. When a modifier key such as an Alt key, a Ctrl key, or a Shift key is pressed and then immediately released, the set of key codes is switched to another if no other modifiable key stroke is inserted during the press-and-release operation. Consequently, multimedia hot keys will be obtained by switching the key code set to another set of key coding that represents individual multimedia functions.
