As you work on projects, you might encounter broken links. A broken link is a reference to a topic that no longer works (it is invalid). Although the program provides safeguards so your projects do not get saddled with these unwelcome bugs, they can still happen. Sooner or later, you will most likely deal with some.
The Project Manager provides a quick and easy way to identify broken links. A special Broken Links folder displays the names of all deleted or missing topics that are referenced in your project.
Additionally, the Tools menu provides options for identifying and fixing broken links. These options include:
Show Topic Links: Displays the topic in Link View where you can graphically view broken links to and from the topic. Broken links are represented as red lines in Link View.
Show Topic References: Identifies all references for a single topic. Use it to find out if the topic is referenced in the table of contents or index, and to find out if other topics link to it.
Resolve Broken Links: Identifies all missing or deleted topics that caused broken links. Use it to find out where the broken links originate from and to restore topics.
Edit Topic References: Enables you to look up references for all topics in your project. Use it to find out where the references originate from and to modify them.
Edit External Topic References: Identifies all external topics (remote links, URLs, etc.) that are referenced in your project. Use it to modify these references and remove them from the project.
