Like many others, this wiki recognizes two or more capitalized words, run together without spaces, as links or references to other pages in the wiki.
Like this: WikiWord.
If you really want spaces, you can use underscores: Wiki_Word
This wiki also recognizes simple hierarchies, using Unix-like paths. "Sample/CategorizedWikiWord" gets displayed like so: CategorizedWikiWord, while still being quite different from CategorizedWikiWord (which looks the same but has no category).
If you need to write something that looks like a WikiWord, but isn't, you can prefix it with a < > (without the space), to get this effect: WikiWord, or put quotation marks around it: "WikiWord".
