I would like to adjust the margin for sections, subsections, etc. I came across a suggestion that you can use setuphead with the beforesection and aftersection options to do something like this, but I tried this with MKIV, and beforesection and aftersection appear to have no effect (see the example below). Recent documentation doesn’t show these as parameters for setuphead. How do I do this with MKIV?

Example:

\setuphead[section] [margin=0.5in, beforesection={\startnarrower[left=0.5in]}, aftersection={\stopnarrower}]

\setuphead[subsection] [margin=1in, beforesection={\startnarrower[left=1.0in]}, aftersection={\stopnarrrower}]

\starttext

\chapter{chapter}

This is a chapter

\section{section}

This is a section

\section{subsection}

This is a subsection

\stoptext
