I like the feature within Word that shows two pages on the screen side-by-side (not using the "View Side by Side" feature, but simply editing the document at a high enough resolution with the zoom low enough to fit two pages next to each other). It does this automatically, and I appreciate the feature. But it drives me crazy that when I'm editing the document and I'm at the end of Page 1, I hit the down arrow to scroll to the next line in the document, and instead of going to the first line on Page 2 (which is the next line in the document), it goes to the first line on Page 3 (which, while technically below the current line on the screen, is not the next line in the document).
I can see why this might make sense for someone viewing a document, but for document editing it's very counter-intuitive and distracting. I haven't been able to find a way to change this behavior, but it's remarkable to me that this isn't configurable.
