To be clear, I am not asking for function right, which sends me to the end of document or space, which scrolls one screen height. If I am viewing page 31, I want to jump so that the top of 31 is at the top of my viewer, or the bottoms of 31 is at the bottom. I read a lot of articles on my macbook, and the pages are always to long for single page viewing, so I have to manually scroll through them, which is annoying and bad more my flow.
If there's no answer to my exact question, is there a way to scroll down a fixed amount that isn't a whole screen-height? Is there another PDF viewer that has the functionality I want? Thanks for any help you can provide!
