Wiki

I cant find any documentation on how to create an external link to a subject heading in dfwiki.
I want to link from another wiki or from a webpage

The solution I found was that

Apparently dfwiki table of conetnets comes from automatically generated anchors which are labelled toc1,toc2 etc.
Once you figure out what your subheading is you can link with the syntax

http://wikiaddress#toc1

I cant figure out how to insert anchors manually and have them come up as an option to link to in an external document?

Any similiar tips
