Keyboard Cleaner
This is a cool donation ware program. It allows you to clean your keyboard and not have the key presses send your mac into a frenzy nor do you need to turn your mac off. Very nice!
“I created Keyboard CleanerIt 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.”
