What is the purpose of a “skip navigation” link? Why is this beneficial to people who are blind? What other group would benefit from “skip navigation” links?
What will be an ideal response?
) A “skip navigation” link allows a person to go directly to the content of the page and thus jump over all of the links in a navigation bar. Without a “skip navigation” link, blind users are forced to listen through the navigation bar on every page that they encounter. This takes time. Another group that would benefit from “skip navigation” links are people who are not using a mouse and are using some alternative input method such as a head wand and an online keyboard. Making the same head movements repeatedly to tab through all of the links in a navigation bar can get tiring
