An input device for inputting commands to a host computer includes a base. An upper housing defines a plurality of control buttons for inputting commands to the computer. The base and upper housing are movably coupled to each other to enable the mouse to be placed in a collapsed position and a raised position. A release button is configured to actuate and facilitate raising of the mouse from the collapsed position to the raised position, the raised position placing the mouse a suitable state for inputting commands to the computer using the control buttons.
