Can't say this is really a big deal to me. I think 50 % or 75% is not
enough I'll settle for page scrolls 90% :-)

I've had a quick look at your other patch on ticket #8139 and it does
not look correct. A widget should always pass false back if it doesn't
handle a keypress to allow other handlers like the ones in
MythScreenType to handle them.  Things are  a little more complicated in
the browser widget because the arrows have a dual function. Sometimes
they are used to scroll in the browser but they are also used to shift
focus to other widgets.  The way it works is when you scroll in one
direction and can't scroll any further then the focus is moved, I know
it's a source of frustration for many users but the same problem exists
in other parts of mythui like the buttonlists. In any case  that has
nothing to do with the bug you are trying to fix.
