SkipTo.js

The SkipTo.js script is a replacement for the old school “Skip To Main” link, (so please use it as such)! The SkipTo script creates a drop-down menu consisting of the links to important landmarks and headings on a given web page. Once installed and configured, the menu makes it easier for keyboard, voice recognition and screen reader users to quickly jump to the desired location by simply choosing it from the list of options.
