Moving through document page by page

I'm new to acrobat and I'm trying to figure out how to do this one thing. I have a transcript I am trying to read and edit on acrobat. I have converted it to pdf and pull it up in Acrobat. I do a batch function to strip out white margins (I'm proof reading the transcript on a tablet with a pen/pencil). I can't figure out how to kind of freeze a centered view of a page and then have my next page come up centered again. That should be easy but since it's a tablet I rotated the document. When I use the bar to advance page the next page is right or left justified on the screen. I have to fool with the advancing bar to center the page again. That takes way too long to do.

I think rotating has added some complexity to this simple task. If that wasn't too clear I'll try saying it another way. I have rotated a page and centered it exactly on the screen where I want it to be and want to hit a next page function and have Acrobat ignore that there was some data I had missed on the previous page because of blank margins. I am finding I go to next page on a rotated document and Acrobat wants me to see what I missed before advancing to the true next page and then that has become off centered again.

Can anybody suggest anything?
