Element.accessKey
The Element.accessKey property sets the keystroke by which a user can press to jump to this element.
Note: The Element.accessKey property is seldom used because of its multiple conflicts with already present key bindings in browsers. To work around this, browsers implement accesskey behavior if the keys are pressed with other "qualifying" keys (such as Alt + accesskey).
