Navigation bars are usually the first thing someone encounters on a page.
For users with speech synthesizers, this means hearing the same links on every page before reaching the interesting content of a page. Other keyboard users, such as some users with physical disabilities, will have to tab through all of these links to reach links further down the page. There are a number of ways to allow users to jump past the group of links. The first link in the group skips over the set of navigation links when selected. Provide a style sheet that allows users to hide the set of navigation links.
