a touch detection surface;
a touchpad display disposed to present visual images at the touch detection surface;
a processing resource interfaced with the touch detection surface and touchpad display; and
a non-transitory memory interfaced with the processing resource and storing instructions that when executed on the processing resource cause the touchpad touch detection surface to detect cursor movement inputs and to selectively present control icons of the application at the touchpad display having a brightness set based at least in part by ambient light conditions detected by an ambient light sensor;
