An electronic device includes a display and a keyboard having a fixed part and a movable part. The movable part moves between an open position and a closed position. The size of the electronic device remains unchanged when the movable part is in the open and closed positions. The movable part covers a portion of the display in the open position, and has back keys which cover the display portion and are inaccessible by the user. In the closed position, the entire display is exposed, and front keys of the movable part are inaccessible and cover keys of the fixed part.
