A WikiName is a word that uses capitalized words. WikiNames automagically become hyperlinks to the WikiName's page.
When you click on top on the page title (i.e. WikiName on this page), you will see a list of all pages that link to the current page. This even works on pages that are not defined yet.
A link with a rendering in grey means that the page is not yet defined: you can click the page name to offer a definition (e.g., NoSuchPageForReal). If you click on such a link, you will see a default page that you can edit; only after you save the page will it be created for real. A list of all pages that are not yet created but referred on another page is on WantedPages.
To escape a WikiName, i.e. if you want to write the word WikiName without linking it, use an "empty" bold sequence (a sequence of six single quotes) like this: Wiki''''''Name. Alternatively, you can use the shorter sequence "``" (two backticks), i.e. Wiki``Name, or with an exclamation point in front !WikiName
