I wasn't talking about the Red circle at the top of the screen, I don't need that. I was referring to simply having SnagIt happen, do it's thing and get out of the way.
You still want to have a step where you click a desktop button and then have to initiate the capture anyways? Okay.
Click on Start, find SnagIt in the list, right-click and select Pin to Taskbar (bottom row).
