Oh, speaking of these functions...
When I do the nudge up or down, lines get pooted out to scrollback. If
there is any way to nudge without that happening, it sure would be nice.
That sounds like a feature of the terminal emulator (or 'screen')
which lynx can't address.
But it doesn't happen when paging up/down, so what's different about lines?
As I understand your first comment, what is happening is that the curses
(or whatever) library is updating the display by asking the terminal to
scroll up/down by a few lines, then painting new text in the blank area.
For a pageup/down, it could be simply repainting the whole display -
if the whole screen changes, there's no point in shifting everything
up/down to paint over it. (Even for a half-screen, that depends on how
long the shifting is supposed to take, and whether the curses library
notices this would be a good solution).
