Changes
→Your Own Title Styles
Sometimes the possibilities of <cmd>setuphead</cmd> aren't enough. You can define
your own styling commands, as shown in the following examples.
===Start the title in the margin===
This very simple example shows how to start a title within the margin, rather than at the text's edge
<texcode>
\setuphead[chapter][alternative=margin]
</texcode>
This looks like
<context>
\setuphead[chapter][alternative=margin]
\chapter{Sample chapter}
Number is in margin, not at text edge.
</context>
===Expanded chapter titles===
