You can find PDF pages that you viewed earlier by retracing your viewing path. It’s helpful to understand the difference between previous and next pages and previous and next views. In the case of pages, previous and next refer to the two adjacent pages, before and after the currently active page. In the case of views, previous and next refer to your viewing history. For example, if you jump forward and backward in a document, your viewing history retraces those steps, showing you the pages you viewed in the reverse order that you viewed them.
