I was trying to look up some details while helping another user with local navigation and noticed that FANDOM's help page is definitely missing some things. I know because the wiki I admin uses some magic words that aren't even mentioned on the page. So I tried to see if there was external documentation available but I don't know what the extension is. Is this a standard extension/feature? If so, what is it called? If not, does Wikia have more thorough documentation elsewhere?
