List of headings missing under the Navigation toolbar (Mac OS)

Under the navigation button in the toolbar I can only see the RECENT Drafts list - and not the list with all the headings of my document. Is there a specific setting that I am missing?

Just to make sure that you do have headings in the document, you could try hitting the “navigation” menu item. If you don’t see any headings there (should be both headings in your current document and the list of recent drafts) it confirms that there aren’t actually headings in the draft you’re working on.

Thanks for your prompt support. Actually hadn’t any headings in my draft. Got it now.
