CSToggle is a teeny application that has one purpose in life - to toggle on and off the Control Strip display. If you run it while the Control Strip is showing, the Control Strip disappears. If you run it while the Control Strip is hiding, it re-appears. That's all!
You can somewhat hide the Control Strip by clicking on the end tab, but even if you do, a little tab still shows in the foreground, and can still eclipse items behind it. You can hide the entire Control Strip by going to the Control Strip control panel and choosing "Hide Control Strip", but this a bunch of extra steps. I normally keep CSToggle in my Apple Menu, so that it is always accessible.
If the Control Strip software isn't loaded (you haven't booted your computer with the Control Strip control panel present) then running this program will cause nothing to happen.
This program runs on any Macintosh that is running the Control Strip software. It is freeware.
