The Web without hyperlinks would be unthinkable and the same applies to interactive help and documentation. Hyperlinks between topics are what makes your help genuinely useful. You can create links to topics and specific places in topics. In addition to this you can create links to pages on the Web and external files, and you can also create special links that execute scripts.
This tutorial shows you the basics of creating hyperlinks to topics and specific positions in topics. For full details on working with hyperlinks see Links, Anchors, Macros, Scripts and HTML.
