Skip links are links to another part of the page that allow visitors to navigate their way around a web document, without having to cycle through a huge list of links.
A common misconception is that skip links are just for screen reader users. This is probably borne out of the fact that a lot of people still regard accessibility as being primarily for those with visual impairments.
