"this" refers to keyboard shortcuts for radio buttons. The thing
you're asking me to implement.

Perhaps Matthew is willing to add this stuff to mred v1, but I suspect
he'll tell you to just wait for mred v2.

I guess I can try doing something simple. How about making the down
arrow key move the focus back down into the hier-list, selecting the
first thing and making the up arrow key move the focus back down into
the hier-list, selecting the last thing. As far as getting outside of
the hier-list, up from the topmost entry could move the radio button
selection and down from the bottom-most could move the radio button
selection too.
