It means that if you enclose an external link with it, it'll show up like a normal link.

For example: http://google.com

You can see the little arrow thing indicating it's external, but if you do http://google.com (which is http://google.com ), it'll show up like a normal link instead.

Edit: looks like Jr Mime beat me to it
