To see a list of all of the pages in a namespace (the main namespace has 6,900,986 articles, plus millions of disambiguation pages and redirects), click on Special pages in the toolbox menu on the left side-bar of your screen. At the top of the list that appears is the entry All pages. Click on that, and a pull down menu (to select a namespace) and a search box for entering a starting pagename appears. The namespace listing will start at whatever spelling you place in the searchbox.
To get a list of only pages starting with a particular string of characters, click on All pages with prefix instead.
