For instance in the reference manual...

That would be fine...

I see. Yes, that would work. 

But I was actually thinking of a more direct
display, in the same coordinate system that 
"set margin" takes - in other words, using 
the current character position of the margin.

What variables hold the key position? When I
do "show variables all", nothing seems appropriate.
