While creating or working on a style-based document, it is very helpful to know the overall structure of the document that you are working on. Scrolling through a long document does provide this information, but it is not a seamless experience.
The latest release of FrameMaker provides a single unified view of the headings or structure of your current document. Open the new Navigation View, and the structure of your current document is displayed in the Navigation View panel. The logic used in this feature gives you a list of all headings and subheadings within your current document.
To launch the Navigation View, go to View > Panels >Navigation View or use the shortcut keys Esc, n, v.

Clicking on a heading in the Navigation View takes you to the heading content. Use the context menu to quickly navigate to, expand or collapse topics, or even delete an entire heading (or topic) from your document.
For more information, see Navigation View.
