Abstract

A handheld computer includes a bar retained in an interior. A first button structure is accessible on an exterior surface of the handheld computer. A member joins to and extends between the bar and the first button structure. The member enables the first button structure to move into an actuated position without undergoing a radial motion about the bar.
