ABSTRACT:
A portable electronic device is provided comprising a user input device capable of adopting at least three pre-determined positions, each of which enables an associated function to be actuated, and of adopting two pre-determined positions simultaneously. The portable electronic device further comprises a device for presenting information to a user and a processor for receiving inputs from the user input device and altering the operating state of the portable electronic device accordingly. The portable electronic device is operable to scroll through information items presented to a user and the user input device is arranged to present at least two scrolling speeds. A first scrolling speed is selected when the user input device is placed in a first pre-determined position and a second scrolling speed is selected when the user input device is placed in the first pre-determined position and a second predetermined position at the same time.
