evidence is that this didn't get out before, so here it is again.
there's a stupid mistake in the implementation of left and right
arrows.  the other change here is that i tweaked the parameters
so the up and down arrows go 1/3 page and page up and page
down arrows go 2/3 page.

i hope this is it for a while.
