Thank you for the reply - but the keyboard "Page Up" and "Page Down" have a different behavior in Preview than "Next Page" / "Previous Page".

To see the difference: 
1. Open a multi-page PDF in preview. 
2. Zoom In on the PDF until the entire page doesn't fit in the window - scroll windows appear. 
3. Using "Page Up" / "Page Down" on the keyboard it will scroll down the page first, and then move to the next page as necessary. (This is what I want) 
4. "Next Page" / "Previous Page" jumps to the top of the next/previous page, and doesn't scroll through the rest of the page.

Since I'd like to sit back from the computer and read the PDF, I need to zoom in pretty far (thus the need for the remote). So a "Page Up" / "Page Down" option would be great.

Thanks!
