In one embodiment, the control keys are designed to be used with an alternate display orientation of the attached mobile device. In one embodiment, the control keys are control keys of a game pad. In one embodiment, the cover is U-shaped. In a wireless mobile phone embodiment, the cover is attached to a rotabable sub-section of a pivotable section.
