Leopard Dock/Finder tip

There's a cool thing that I discovered you can do in Leopard:

1. start out without any Finder windows open


2. drag an item from the desktop onto the dock icon for the Finder (don't let go!)


3. press space - and a new Finder window appears!


4. you can then drag the file to the desired location as you normally would

(it's possible that this worked on Tiger, but I don't have an easy way to check)
