When you enclose certain codes in double curly braces, you get all sorts of interesting results:

{{PAGENAME}} - the title of current page, with regular spaces between each word of it

• {{PAGENAME}}

{{localurl:{{PAGENAME}}}} - a fragment of the URL that refers to the page you put the code in (note that the page title has underscores between each word)

• {{localurl:{{PAGENAME}}}}

{{SERVER}}

• {{SERVER}}

{{NAMESPACE}}

• {{NAMESPACE}}
