All, I have an error here: \setupcolors[state=start] \startuniqueMPgraphic{demo circle} path p; p:=fullcircle xscaled \overlaywidth yscaled \overlayheight; fill p with color .85whwite; draw p withpen pencircle scaled 2pt withcolor .625red; \stopuniqueMPgraphic \defineoverlay[demo circle][\uniqueMPgraphic{demo circle}] \starttext \input tufte \framed[background=demo circle]{This text is overlayed.} \input tufte \stoptext When I press "e" at the question prompt when the compiles stop, vi opens the file overlay-mpgraph.mp and deposits me at the end of this file. What I'd rather have is to be taken to the line in overlay.tex in bbedit. I tried this in my .bash_profile: export TEXEDIT="bbedit +%d %s" To no avail. Any other Mac users on this list have bbedit set up correctly?
