You can think of your lesson header as a map of where you are and where you can go.
Finding your way around a lesson
The title of your lesson and the course to which it belongs always appear in the top left-hand side of the header, so you can know exactly which lesson and course you are in at any time. The page number and page name are also listed in the header, and open into a dropdown menu that shows you where you are within the lesson itself. You can jump to any page using this dropdown menu, or flip forward and backward through the lesson pages using the blue arrow keys on either side of the page. Selecting in the top right of the header will return you to your homepage.
