Do you mean linking other articles within a name? All you have to do is click on the link tab (little chain symbol) that's next to the italicize and bold options at the top of the page while editing. After clicking the link tab, type in the name of the article you want to link and confirm it. If it's a legitimate article the text will be blue.
