I was talking to someone the other day [EDIT: Datapath, can never remember which handle he uses] and he gave me an interesting idea. Just like when you hold down the "Back" button to clear the entered number, if you hold down the tab then you will get it refreshed.

This won't scale obviously if people want more functionality but it conceptually fits. Its just not too discoverable, like the back button.

Now I just need to get around to packaging it up...
