New pages created in a Moodle Wiki are not necessarily interlinked. The Map tab lists pages for a wiki in alphabetical order by name, and can be used to move from page to page. The word(s) used to create a new page are also the name of the new page.
Example: If you create a new page by typing the text [[My pet]], your new page will be called My pet
