You can also use BWD's Chroma to create a navigation menu by placing a Column stack inside it with Paragraphs containing text links to #ref links on the page. You can use the ScrollTo stack to create the link markers and delete the ScrollTo buttons.
Or you could use floating buttons or a button bar. Probably, the easiest way is to use Foundry's excellent ButtonBar set to a transparent background to do this.
That will give you a simple sticky or fixed navigation menu that will link to markers in the page. If you want a Smooth Scroll effect then the Tsooj ScrollTo stack is a great and easy way to achieve smooth scrolling to a marker.
The standard Foundry is very close and I would very much welcome a way to use Scroll To functionality in a Nav Bar or even a ButtonBar.
