Navigation

The page and navigation elements on a site follow a logical and intuitive tab order. The tab order is the order in which you move the focus from one UI element to another by pressing the TAB key. In addition, two important options ? the Turn on more accessible mode link and the Skip to main content link ? are the first two options in the tab order. If you want to turn on More Accessible Mode, you can do so by pressing the TAB key after the page in the browser has active focus. In addition, if you want to skip repetitive navigation links and go directly to the main content area of the page, you can do so by pressing the TAB key until you reach the Skip to main content link.

In addition, the pages in a Windows SharePoint Services 3.0 site use breadcrumb navigation links that identify where the current page or site fits into the overall hierarchy of the site or site collection. These navigation links appear near the top of most pages, under the page name. For example, if you browse to a folder named Reports in the Shared Documents library for the Contoso site, the navigation links may display Contoso > Shared Documents > Reports.
