Doc-To-Help does not provide an interface for defining arbitrary topic navigation sequences, but instead derives them automatically based upon the order of topics in each source document. By default, only paragraph styles with a numeric outline level participate in the navigation sequence.
To control whether topics created with an active style are navigable:
1. On the Icon bar, click Project.
2. Select the Paragraph Styles item from the left pane.
3. Select the paragraph style to be edited from the right pane.
4. From the property pane, modify the AutoNavigate property value as desired. Setting the value to True allows the topic with the selected style to be navigable.
