Quick search in Mail with an email address

Hawk Wings does it again with a great tip for quickly searching by someone's email address in Mail. All you have to do is either drag an email address from a Mail message to the search field to search for that address, or simply drag an email from the list to the search field to search with the sender's address.

One of those smack-yourself-in-the-head tips that's almost too simple and obvious, but I figured I'm not the only one who didn't know this. (I hope!) Also, I'm running Tiger so I'm working with Mail 2.0. If anyone on Panther or Jaguar wants to sound off in the comments to let us know if this works in those versions, please do.
