While I was reading 'In the Details' to learn more about grid- typesetting, I could not comprehend the examples with grid={broad,...}.
Then in section 1.8 I read that grid=line should be a shortcut for grid={broad,high,depth}.
Section 1.8 deals \exclusively with \externalfigure. Apparently the grid option for sectioning commands is handled differently.
In my version of 'In the Details', dated 2002 chapter 1 deals with 'Snapping section heads' and section 1.8 is titled 'Snapping around (broad,high,depth).'
the grid options as discussed with sections, are the ones that are taken care of by the \snaptogrid macro; the grid key in externalfigure is not related to that, it relates to scaling, as in
\setuplayout[grid=yes] \showgrid \setupcaptions[style=smallbodyfont,location=grid,inbetween=]
\defineexternalfigure[enkel] [width=10cm,frame=on,grid=depth] \defineexternalfigure[dubbel][width=10cm,frame=on,grid=depth]

i.e. the grid option determins which way a height snaps (or is rounded);

My original question was not related to \externalfigure or chapter 8 of the Details-Manual at all. This was brought in the diskussion by mistake. In section 1.8 grid=line was introduced as a shortcut for grid={broad,high,depth}. But these two options are differing. Wolfgang
