I'm surprised not everyone knows this trick, but even at Microsoft I occasionally run into people who haven't seen it.
Type a domain name in the address bar like, "tonychor" and hit "Ctrl-Enter". IE will add the "http://www." on the front and ".com" on the end. Lovely.
It's so important to how I work that I can't use browsers that don't, even otherwise great ones like iRider.
