Instant Properties

Here's a quickie way to view the properties of a file or program.
If you need to get the properties for something (like an icon, for instance), just hold down your ALT key and double-click it .
Instant properties!

Try it with "My Computer" or one of your regular desktop icons.

And yes, I know that you can also right-click an item and select "Properties" from the resulting menu. I just thought this was cooler.
