How to restore the Show Desktop icon in QuickLaunch

Have you ever accidentally deleted the "Show Desktop" icon in the QuickLaunch toolbar, and couldn't figure out how to get it back. The procedure for getting the "Show Desktop" icon back if you delete it isn't exactly intuitive. Here's what you do:
1. Click Start | Programs | Accessories and click on Notepad to open it.
2. Type the following, exactly as shown:
[Shell]
Command=2
IconFile=explorer.exe,3
[Taskbar]
Command=ToggleDesktop
3. Save the file with the name ShowDesktop.scf
4. Drag the file's icon onto the Quick Launch toolbar (or the desktop if you prefer).
