Hi Kelly and welcome to our community
Whether you may do this will depend on whether you are
creating WebHelp or a Compiled .CHM output. I don't believe it will
work with WebHelp. If you are creating a compiled .CHM, first off
make sure your primary layout is configured for Microsoft HTML
Help. If it isn't, you won't see the option I'm about to point you
to.
Once you cross that hurdle, click inside a topic and choose
Insert > HTML Help Controls > WinHelp Topic...
Hopefully that helps some... Rick
