Learn how to make a chapter instead of containing its own separate content, serve as a link to another chapter or a specific location in another chapter. 

Turn a Chapter into a Link

1. Click on Chapter properties. 
   The Chapter Properties window will appear.
2. Select the chapter that you want to link to from the drop-down box under Link to Chapter.
3. Select Beginning of chapter or your previously set anchor from the drop-down box under Anchor.
4. Click OK.

And now you're done.

If you want the link to go to a specific location in another chapter, you will first need to set an Anchor to mark where the link should go. Read more Add an Anchor.
