Shift key together with F1, F2, F3 keys provide several flexible functions in usage. When the Shift key is OFF (not lighted), Rdial key is used for re-dialing, Disc key is used for disconnecting the call, and Conf key is used for creating a conference. If the Shift key is pressed once or more than once, shift state changes. Shift states are indicated and distinguished with the back-ligthing state of the key. Shift key may be fast blinking, slow blinking, or continuously lighted. In each of these shift states, a different function can be programmed for F1, F2, F3 function keys. In other words, when the Shift key is OFF, F1 key is for redialing. When the Shift is fast blinking, F1 key may be for another function. When the Shift is slowly blinking, F1 key may be for some other function. When the Shift is continuously lighted, F1 key may be for a completely different function.
