Has anyone already developed a simple way to control the scanner illumination - ie turn on or off. This request is for the MC3190 with an imager, but the same code should be relevant for other mobile computers with the SE4500 imager.  I know I can do it using Ctlpanel, but what I  am looking for is an easier method.  Ideally I  would like to remap a key function to be able to toggle the illumination.
