Re: How to place "Content" and other chapter-level titles the same vertical distance from the top?

[Denis Maier via ntg-context <ntg-context@ntg.nl>]

This example from the wiki does not run anymore with LMTX:
You get the error message:
I've run across a '}' that doesn't seem to match anything. For example,
'\def\a#1{...}' and '\a}' would produce this error. The '\par' that I've just
inserted will cause me to report a runaway argument that might be the root of the
problem.

Maybe some expansion thing. Don't know, but consider this :

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\setuppapersize[A6][A6] 
\setupbodyfont[8pt] 
\define[2]\MyChapterCommand{#1 #2} % does work
%\def\MyChapterCommand#1#2{#1 #2} % does not work
\setuphead[chapter][ 
        command=\MyChapterCommand, 
        ] 
\starttext 
\startchapter{test} 
\input tufte 
\stopchapter 
\stoptext
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

So, this here should get you started:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\showframe
\setuppapersize[A6][A6]
\setupbodyfont[8pt]
\define[2]\MyChapterCommand%
  {\vbox to 15mm\bgroup
    \vss
    {#1\blank #2}
    \egroup}
\define[1]\MyTitleCommand%
  {\vbox to 15mm\bgroup
    \vss
    {#1}
    \egroup}
                
\setuphead[chapter][command=\MyChapterCommand]
\setuphead[title][command=\MyTitleCommand]
\starttext
\chapter{test} \input tufte
\title{test} \input tufte
\stoptext
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

I bet there are easier solutions, maybe use framed instead of vbox.
