All structure heads, regardless of level, get a location number in the
order in which they appear. Like so (see also MWE at bottom of this
e-mail):
\section{Alpha}
% location number: 1; type: section; section number: 1
\section{Beta}
% location number: 2; type: section; section number: 2

\subsection{Noot}
% location number: 4; type: subsection; subsection number: 2
\section{Gamma}
% location number: 5; type: section; section number: 3
\namedstructureheadlocation{X} then returns the location number of the
current X, where X is the name of a structure level (e.g. 'chapter',
'section', etc.)
If you ask for e.g. \namedstructureheadlocation{chapter}, and you are
not in a chapter, then 0 is returned.
Anything missing?
@Marco: sweet job on
http://wiki.contextgarden.net/Command/definelistalternative. I have
taken the lazy liberty of redirecting
Command/currentlistentrylocation
Command/structureheadlocation
Command/currentlistentrynumber
etc to that page for the now, so that they at least appear in the list
of commands.

a location number is some kind of unique internal reference, a pretty
old feature btw, dating from the early days of context, when complex
interactivity was added, but it comes in handy here

Hi!
How do I highlight the current chapter in the table of contents? The
TOC is displayed on each page. For illustration I misused the
interaction colour, which of course only works for the first page of
a chapter.
\setupheadertexts
[\setups{headlist}]
\startsetups [headlist]
\framed[align=normal, frame=off]
{\placelist [chapter] [alternative=f, criterium=all]}
\stopsetups
\setupinteraction

\startchapter [title=beta] \page\input knuth \stopchapter
\startchapter [title=gamma] \stopchapter
\stoptext
You can use the marking mechanism to get the title of the current chapter.
The problem for the solution below is to get a expandable version of the
list entry because \currentlistentrytitle itself isn’t expandable and can’t
be used in \doifelse. Instead of using \ctxcommand better ask Hans for
a raw/expandable version of the tile/pagenumber commands.
\setupheadertexts
[\setups{headlist}]
\startsetups [headlist]
\framed[align=normal, frame=off]
{\placelist [chapter] [alternative=highlight, criterium=all]}
\stopsetups
\definelistalternative

\letvalue{\??internalreference\s!default}\!!zerocount
\def\storeinternalreference#1#2%

and in \strc_sectioning_register add:
\storeinternalreference\currentstructurename\nextinternalreference
then we can say:
\startsetups [list:highlight]

\startlinealignment[middle]
\doifelse\currentlistentrylocation{\structureheadlocation{chapter}}
{\color[red] {\currentlistentrytitle}}
{\color[blue]{\currentlistentrytitle}}

which is just comparing numbers (so one can also say:

\ifnum\currentlistentrylocation=\structureheadlocation{chapter}\relax
\color[red] {\currentlistentrytitle}

Header and footers are added and calculated after the page is finished
but when you put a text in a layer it is fixed at this moment.
The problem in your example with the custom list alternative is that
you haven’t defined it when it is needed, when you put \definelistalternative
