this page is meant to be viewed in a specific, linear fashion. it can be viewed otherwise, but, in order to understand, it should be looked at in the following way. each section is meant to be gone through, in order. going through each section means using the right icon button until you've returned to the beginning of that page; at which point, the center icon should be used. when there are no more pages to view, and you are back where you started, you will have seen the page as it was meant to be seen. other ways are fine too. but this is the one it was designed for.
