Two screenshots comparing how Word's Navigation Pane would appear with different uses of Heading tags for a fiction manuscript. On the left is a version showing a non-hierarchical text list of the book's scenes, such as "Sara loses job", "Joe day 1 at vet clinic", "Backstory - choice of town" and "Backstory - choice of career". On the right is a version of the Navigation Pane with the same list of scenes but with heading tags applied so that some scenes are clearly nested within others. In this example, "Backstory - choice of career" is now nested within the "Joe day 1 at vet clinic" scene, and "Backstory - choice of town" is now nested within the "Sara loses job" scene.
