To check if a logical heading structure has been used:
To examine the heading structure, Run the accessibility checker: "Skipped Heading Level" will show if headings are not set correctly.
To check the heading structure:
-
To view the current structure, open the headings (navigation) pane: CTRL + ALT + SHIFT + H.
To view the current structure, open the headings (navigation) pane: On the View Tab, in the Show Group, Select Navigation Pane.
Note: Only headings that have been properly formatted with heading styles will show in the Navigation Pane. All headings should have a heading style applied and should show in the Navigation Pane. For instruction on setting heading styles, see the guidance for Unstructured Document.

To set a logical structure:
-
Open the Outline View: On the View Tab, in the Document Views Group, select Outline.
-
The Outlining Tab opens in the Ribbon. The document is shown in Outline View.
Use the controls in the Outlining Tab to set a logical heading structure. The level of the heading under the cursor is shown in the Outline Tools Tab. The controls in the Outlining Tab can be used to promote/demote headings, move headings within the document, show or hide formatting, and more.

Use programmatically discoverable headings to logically structure content.
