I want Pagedown to exit copy-mode if it is pressed at the bottom of the scrolling page.
I have tried using if-shell with tests involving #{scroll_region_lower} and #{scroll-region-upper} but they don't seem to give the right results.
Is there a variable I can test that will tell me where in copy-mode scrolling I am? The top of the page displays the position, I need a command to return the 0 from [0/2270].
