The butterfly keyboard is split into two roughly triangular pieces that slide as the laptop's lid is opened or closed. As the lid is opened both pieces slide out to the sides, followed by one piece sliding downward. The two halves mesh like jigsaw puzzle pieces to form a keyboard 29.2 cm (11.5 in) wide which overhangs the sides of the laptop body. Conversely, as the lid is closed one piece slides back, then both slide inward until the keyboard can be covered by the lid. The movement of the keyboard is driven by a cam on the lid's hinge, so the motions of the keyboard parts are always synchronized with the movement of the lid.
