Abstract
A portable device is described which comprises a user input and a processor. The user input has a key with a plurality of functions. It has a first function when the device is in a first state and a second function when the device is not in the first state. The processor is arranged to determine the state of the device and to perform the first and second function depending upon the state of the device. When it performs the second function, the processor returns the device to the first state.
