Untested but this should work:

\section{This title is long \nomarking{enough to cause problems in the headers and footers}}

Everything inside \nomarking{} will not be shown in the headers or footers.

See https://wiki.contextgarden.net/Command/nomarking

Hello,

How can I clip long markings in the header?

See this MNWE, where the two copies of section title collide on page 3.

---------------

\starttext
\setupbodyfont[20pt]
\setupheadertexts[section][section]
\section{One}
\section{Two}
\page
\section{Three}
\page
\section{Long Title for Section Four}
\page
\section{Five}
\stoptext

------------

How can I clip the title to a fixed length (5cm?) and perhaps add "..." at the end for longer titles?

Is it possible to provide an alternative shorter section title within \section?

Thanks,

Mohammad
