Leopard/Tiger: Show Alias Originals Using A Keyboard Shortcut

If you use aliases often (I've written more about aliases here.) you might want to see where the original file is. Well, the way I always did it was to right click on the file and select "show original". Well, I have found a new, much better, way of doing this. All you have to do is hit Cmd-R, or, go to (in Finder) File>Show Original.
