[NTG-context] Bold math in section titles ??

Hi! Is it possible to activate bold math printing in a chapter/section/subsection title? In the example the numbers withing math mode (and the greek symbols) are set in regular style, while the rest of the title is printed in bold. Best regards Michael -------------- Example: \setuphead[chapter][textstyle=bold] \setuphead[section][textstyle=bold] \setuphead[subsection][textstyle=bold] \starttext \chapter{Test} \section{$1 2 3 \alpha \beta \gamma \delta - 1 2 3 A B C D } \stoptext
