Keyboard Cleaner shields your desktop and intercepts every keystroke you might accidentally make Keyboard Cleaner comes in handy when you want to clean your keyboard, but you are afraid you might trigger a command or change or delete some of your current work beyond repair and undo. Of course you could save and close everything. Sometimes however, it is just not what you want.Enter Keyboard Cleaner. It shields your desktop and intercepts every keystroke you might accidentally make - except for Command-Q.Needles to say that this was an educational project for me. While trying to create something like Visor for iTerm about a year ago I needed to figure out how to make a fading window without delving into Quarz Graphics too deeply.Of course, Keyboard Cleaner comes free of cost. I even made a clunky video of how it works. Keyboard Cleaner is a Universal Binary and works with multi-monitor setups.
