Double Tap Gesture With One Finger On the Finder Icon On The Dock Shows Just the Finder/Desktop

Hi. I was looking for the fastest way to show just the Finder/Desktop. I double tapped with one finger the Finder's icon on the Dock and that showed just the Finder/Desktop. It's good it has it. It's easier to show the desktop on Windows but not by much, though Lion does it more elegantly. Double tapping on the other app icons will show only that app. It's good it has this gesture. This is on 10.7.2 Lion (Snow Leopard may have the same). The only drawback is you can't actually go to the Finder and hide the other open windows and apps, it just shows it.
