Help:TableOfContent

From NSDLWiki

Adding or Removing a table of contents (TOC)

A TOC is added automatically as soon as you have more than three headers. To add one with fewer than four headers, type __FORCETOC__ anywhere on the page or __TOC__ at the position where you want to have the TOC.

To remove a table of contents from a page, add __NOTOC__ to anywhere on the page. The __ character before the commands is two _ (underline) characters together.
