I checked this.

But it is the same document!

Section 1.8 deals there with 'Snapping section heads' too.

Oops excuse me. I was reading _chapter 8_ . I'll try to
find the difference

Ok: yes they are definately different, but at the moment I don't
know why. I predict that it is the manual that needs fixing,
though.

\arg is one of the verbatim macros, like \type, \typ, \tex
and is describte in 'cont-enp.pdf' on page 101.

The description looks a bit incomplete: (the command encloses the 
text with .)
(Can someone, with the right to do that, add this to the list of 
typos, please?)

The definition of \arg is in 'core-ver.tex' and copying this 
in a separate file works as expected:

\starttext
\unprotect
\def\setgroupedtype
  {\let\currenttypingclass\??ty
   \initializetype
   \catcode`\{=\@@begingroup
   \catcode`\}=\@@endgroup}

\unexpanded\def\arg{%
\groupedcommand{\setgroupedtype\leftargument}{\rightargument}}
\protect
\arg{bla}
\stoptext

So there must something be damaged.

Well, \arg is also defined in math-tex.tex:

   \definemathcommand [arg]     [nolop] {\mfunction{arg}}

So there is a double definition.

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]

\starttext

test \placefigure{}                 {\externalfigure[t:/sources/cow.pdf][frame=on,grid=yes]} test \page
test \placefigure{\input zapf\relax}{\externalfigure[t:/sources/cow.pdf][frame=on,grid=yes]} test \page

test \placefigure{}                 {\externalfigure[t:/sources/cow.pdf][enkel]} test \page
test \placefigure{\input zapf\relax}{\externalfigure[t:/sources/cow.pdf][enkel]} test \page

\stoptext

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

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).' 
Is there a newer variant of that manual?

Section 1.8 deals \exclusively with \externalfigure. Apparently
the grid option for sectioning commands is handled differently.

Snapping sectionhead

[wwl]

Hallo!

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}.

But these two variants gave me not the same result!

Try

\setuplayout[grid=yes]
\definehead[Demo][section]
\setuphead[Demo][style=\bfb,
                 before=\blank,
                 after=\blank,
                 grid={broad,high,depth}]
%\setuphead[Demo][style=\bfb,before=\blank,after=\blank,grid=line]
\showgrid
\starttext
\Demo{Agathe}
Bla blubber
\stoptext

Hmm!
