Dear gang,

Trying to get the sectioning numerals in the left margin of the TOC to be
fushright; by default they are flushleft; see attached and below:

=======
\setuphead[chapter]   [conversion=R]

\setuplist[chapter][width=2.8em]

\definecombinedlist
[content]
[chapter]
[level=chapter,
alternative=c,
numberalign=flushright]

\starttext
\placecontent[conversion=R]
\startchapter[title={First},reference={}]   \input ward \stopchapter
\startchapter[title={Second},reference={}]  \input ward \stopchapter
\startchapter[title={Third},reference={}]   \input ward \stopchapter
\startchapter[title={Fourth},reference={}]  \input ward \stopchapter
\startchapter[title={Fifth},reference={}]   \input ward \stopchapter
\startchapter[title={Sixth},reference={}]   \input ward \stopchapter
\startchapter[title={Seventh},reference={}] \input ward \stopchapter
\startchapter[title={Eighth},reference={}]  \input ward \stopchapter
\stoptext
=======

numberalign=flushright would seem to be the governing keyword+value, but
that has no effect here.

For the form of the desired result, see toc-margin_numerals-MURE.pdf:

(note the stopper after each margin numeral!). Thank you in
advance.

Best wishes
