navigation bar
A navigation bar is an element on a web page, often graphical, that contains links to other pages in the web site. Many sites display a single, consistent navigation bar on each page to provide site visitors with a convenient, organized way to browse the important pages or areas of the site. The navigation bar at the top of every page in Web Hosting Help, for example, includes links to Small Business Home and Yahoo! Site Solution and Yahoo! SiteBuilder help you automatically create a navigation bar for your web site.
newsreader
A newsreader is a piece of software you can use to organize and read syndicated content, such as newspaper headlines or blog entries. People who read a lot of blogs especially like newsreaders because they can see the latest entries from all their favorite blogs in one place. My Yahoo! provides a great newsreader option: Readers can subscribe to as many blogs as they like; those blogs' entries appear automatically on their customized My Yahoo! pages.
