Smarter Address Bar
Can't remember the full address of a new website you visited last week? Type a few characters in the new Address Bar and Internet Explorer 8 will automatically recall sites you've already visited based on your entry. It searches across your History, Favorites, and RSS Feeds, displaying matches from the website address or any part of the URL. As you type, matched characters are highlighted in blue so you can identify them at a glance. In addition, you can delete any address in the drop-down box by clicking on the red X. This is especially useful for getting rid of misspelled URLs.

The address bar generates results as you type.
