Alt + F8

Today I was working remotely on a Windows 2003 Server and was creating a new virtual machine within VMware. During the Windows installation it requests you press F8 on your keyboard to accept the licensing agreement. When you do this on the Mac in Leopard (with the default short-cut keys) it shows all of your "spaces". The way to get around this is to hold down the ALT key and press the F8 key on the keyboard, FYI.
