Scrolling between pages works in one of two modes. Either it is continuous, such that as you scroll (slide the hand up) past the current page, the following page scrolls up with it, allowing you to see a good portion of both pages simultaneously. The other mode is where you reach the end of the current page, the following page is not visible until you change pages, at which time you're at the top of the next page, but cannot see the previous page anymore. What is that called? It's a per-document attribute/property. I do not think this is a feature settable in any reader (acrobat reader, foxit reader).
I already know how to view pages side by side or other arrangements. I'm looking to learn the name of the above feature so that I can configure it on a per-document basis.
