In single-page view ↓ / ↑ only added to the pending keyboard scroll, so on a page that fits the window (or once scrolled to the page's end) they did nothing, while the mouse wheel turned the page there. The page view now records, after each frame in single-page view, which page it drew and whether it was at the top and at the bottom of it. ↓ at the bottom (always, on a page that fits) steps to the next page; ↑ at the top steps to the previous page and lands on its bottom, so holding ↑ keeps scrolling back through the document. The edges only count when they belong to the current page with no jump pending, so a stale frame can't turn two pages for one press. Tested by a kittest: Fit page in single-page view, ↓ / ↑ turn one page per press; Fit width, ↓ scrolls through page 1 before turning, and ↑ from the top of page 2 returns to the bottom of page 1.
