MarkupInternalLink [add child]
You can make a link to another wiki page simply by stating the name of the wiki page. For example, the name of this page is MarkupInternalLink.

The name of a page has a special syntax known as a WikiWord. A WikiWord starts with a capital letter and has at least one more capital letter in it. Between the capitals there must be lower case letters or numbers. There cannot be two capitals in a row.
