-              A mechanism should be available to bypass blocks of content that are repeated on multiple Web pages. 
-              When keyboard-only users interact with your site, they use the tab key to jump from link to link. If you have a lot of links at the first of your page in your header or in a menu, they must tab through those every time they come to a new page just to get to the main content. Providing a skip to main content link allows them to easily bypass this.
