Abstract
A portable device which includes a body, a cover and a key. The cover has a closed position for at least partially covering the body, and the key is accessible when the cover is in this position. When the cover is in this an open position, the key has no function, whereas when the cover is in the closed position, the functionality of the key changes depending upon the state of the device. One such function is the muting of an audible indicator provided by a speaker or the like of the device. This may occur, for example, if the key is actuated when the device is a phone and has received an incoming call or if it has an alarm.
