TRAXSYS' Roller Plus line are the most adaptable mouse substitutes on the market. Available in a 2.5" trackball they have six buttons that support left and right click, double click, drag lock, horizontal and vertical lock and cursor speed control. A flashing light indicates the drag button has been activated. The Roller Plus products include a key guard to help users isolate on the buttons. Switches can be easily connected to emulate the mouse buttons with the Roller Plus Switch Box, also included with purchase.
