Multiple skip links can be used
You could create a hidden link before the menu that allows you to skip it, if that's what you mean. When a user tabs onto it, they would hear your instruction and by selecting it they could bypass the menu.

Highlights:
The idea is simple enough: provide a link at the top of the page which jumps the user down to an anchor or target at the beginning of the main content.
Probably the most accessible method for visually hiding skip links is to hide them off screen, then cause them to be positioned on screen when they receive keyboard focus.
Skip links or other in-page links can also be used to allow users to jump to or jump over page content. For example, the Table of Contents at the top of this page includes in-page links to facilitate navigation to page areas. A "skip" link could also be used to allow the user to quickly bypass confusing or potentially inaccessible content, such as ASCII art, complex tables, etc.
