Remember when we talked about typing URLs into the Address bar? IE4 has a showy little feature that makes it easier to enter an address.
Try typing www.actd into the Address bar. If you give IE4 a couple of seconds, it will search through all the Web sites in your History list to find an URL that matches. Should IE4 find a match, it will automatically "complete" the rest of the URL for you. What a showoff, eh?
