How do I create an anchor link from a navigation menu?

I know how to create a navigation menu, and I know how to create anchor links. But I cannot figure out how to create a navigation menu which links to a series of anchor links throughout the page. Specifically, the page I want to modify is:

I used a bunch of buttons to accomplish the task, but this was time consuming and seems kind of unprofessional looking. I would like a navigation menu to accomplish the same thing.
