Thread:Project:Support desk/Table of Contents: Linking to a Separate Page

I have been working on a page (call it MainPage) and it has grown quite a lot over the past few months. The auto-generated Table of Contents now has about 20 items listed. Some of the sections have grown quite big and I would like to move one of them (call it BigTopic4) off MainPage and onto a page of its own.

Is there a way to have the entry for that new page listed in the Table of Contents of MainPage--but have the link for that entry point to the new page?

For the moment, I have left a small section on MainPage called BigTopic4 solely for the purpose of having it included in the Table of Contents on MainPage. The section's only purpose is to direct visitors to the new page, BigTopic4. I would like BigTopic4 to remain listed in the Table of Contents on MainPage, but when people click on the link, I would like them to go directly to BigTopic4's separate page.

How can this be done?
