Hm, interesting...  But having the outline arrows in a third column
(outside the text area) still doesn't let people use the keyboard on the
icons, so from that point of view, just using the fringe isn't any worse.

But that's a good point.

Could we envision "blending" fringe markers?  They're pretty primitive,
so that's probably difficult to achieve.

In general, though, it'd be great if fringe markers could be more
normal.  That is, if we could display general images in that area,
instead of just the monocolour things, defined awkwardly, that we have
today.
