Hi,
There was a question on TeX.SX about an error message

The following MWE shows the same error
\setupfootertexts[\namedheadnumber{chapter}]
\setuppagenumbering[location=,alternative=doublesided]
\starttext
\completecontent
\chapter{Creating device driver}
\section{How to create the}
Chapter text
\stoptext

lua error > error on line 8 in file /tmp/test.tex:

stack traceback:
...uild/src/tex/texmf-context/tex/context/base/strc-doc.lua:904: in
function 'getsectionnumber'
[\directlua]:1: in main chunk
The error is weird because it only appears when all parts of the minimal
example are present. If I comment either or `location=,` or
`alternative=doublesided` or `\completecontent` or `\section{...}`, the error
goes away!
Any thoughts?
The error arises only when there is no aux file. A alternative to
\namedheadnumber{XXX} is \getmarking[XXXnumber].
\setupfootertexts[{\getmarking[chapternumber]}]
Thanks!

You can use the \underbrace and \overbrace commands.
\starttext
\startformula
\underbrace{f(n)}_{\text{Output}} = \underbrace{\overbrace{n}^{\text{Input}} +
3}_{\text{Rule for Function}}
\stopformula
\stoptext
