A user has pointed out a disadvantage of current behaviour compared to
1.2.6, where you could click a scrollbar to give it focus, use left/right
arrow to move the cursor in the track, and still then use Pg Up/Pg Down to
scroll up/down (vertical scrollbar) or left/right (horizontal scrollbar) a
screenfull at a time. Pg Up/Pg Down otherwise scrolled horizontally when the
focus wasn't on a scrollbar. 

Come to think of it, no Pg Up/Pg Down when there is a vertical scrollbar
seems a bit of a loss. Could it be re-implemented after 2.0, while still
being able to move the cursor with left/right after dragging a scrollbar,
and while still letting PgUp/Pg Down over-ride it if chosen as a shortcut?
