Using Jump lists
In order to access jump lists Right-click on a program icon on the Taskbar, like,for example ,Internet Explorer. Notice that you can pin those items to the Taskbar if you wish to.
After you have the jump list open click the first letter of an item to jump between them.
Here is a fine example of the Jump List feature in the Start Menu. This makes it relatively easy to access recently opened items as well.
Periodically you may also want to clear out the jump list history; to do this Right-click on Start and then choose Properties.
Now under the Start Menu tab uncheck one or both boxes under Privacy to clear the Taskbar or Start menu item history or both.
This is an awesome new feature in Windows 7 that makes navigating items a lot faster.
