Articles Anywhere comes with a handy editor button to help you insert the code you need.
Advanced View Site
Better Preview also changes the way the 'View site' link in your administrator works. It will make that link go to the frontend equivalent of that page. It will also display links to any parent pages (like parent category pages when editing an article).
