A portable communication device includes first and second parts, a user input device, and a control unit. The second part is rotatably coupled through a hinge to an end of the first part and configured to be positioned relative to the first part in at least one open position and one closed position. At least one of the first and second parts includes an information presentation unit that is configured to present a first list of items stored in the device for viewing by a user when the second part is in the closed position. The first list includes at least a first item and one or more further items corresponding to the at least first item. The user input device is configured to sense a user selection of a displayed item. The control unit is configured to respond to user selection sensed by the user input device of an item from the first list of items by displaying a second list comprising letters, and to respond to user selection among the displayed letters by modifying the displayed first list of items.
