This small program allows you to activate the screensaver whenever you like, by pressing one of the 'F' keys at the top of the keyboard.
This is useful if you want to leave your computer, and immediately stop anyone from seeing what you are doing (instead of waiting for the screensaver to kick in by itself). Its also a good idea to set a screensaver password if you are using it for privacy.
You can select any of the 'F' keys you want (except F12), so it shouldn't interfere too much with any other programs that are using them at the same time.
