Question to Text Expander Users

In my never-ending quest to find a way to add url shortcut functionality to Safari once I upgrade to Leopard (Ex: I type "mr" and I'm taken to macrumors.com, as defined in a preference) due to the absence of InputManagers, I was wondering if TextExpander worked in Safari's address bar and could provide me with this functionality.

I realize this is only touching on the surface of what TextExpander can actually do, but I haven't purchased it before for the sole reason that it's not something I currently have a real need for.
