I’m sure that a lot of you know that you can choose a file that’s in your Trash and tap the spacebar to get a Quick Look of it (if you’re running Leopard or Snow Leopard, that is). But trying to double-click to open a trashed file results in a snarky little box telling you that you’ll have to drag it out to do that.
I rebuke thee, dialog box.
Fortunately, there’s a way around this. You can click and drag the file from the Trash and drop it onto an appropriate application in your Dock, and that application will then open it just fine, without removing it from the Trash first. You can even e-mail a file that’s in your Trash using this method.
