Umm ...

I could be wrong, but the idea of using

a draw-over-selection was exactly that you don't need

to provide coordinates. The coordinates are the ones of

the selection box.

Every graphical windows usually define xmin-xmax, ymin-ymax,

so, in theory you should simply say, (line (pt xmin ymin) (pt xmax ymax))

... but as i said, i'm an humble beginner in Texmacs, i think it should

be like that, but i can't do it;)

You don't need a graphic, and a small macro can do the job, badly ...
because one have to provide the coordinates of the start/end points of
the line.
It would be great to compute these coordinates (i.e the position, width
and height of the box), but I didn't find a way to get them ...
