Hi Tobias,

I have several equations. But for some of them (lengthy and uninteresting calculations) in the appendix the default fontsize is too big. What is the best way (command) to reduce their size consistently?

Can you play with the following and let me know it this works ok with regards to spacing: \starttext \unprotect \appendtoks \doifdefined{\??fm\currentformula\c!korps} {\switchtobodyfont[\getvalue{\??fm\currentformula\c!korps}]}% \to \everydisplay \protect \definieerformule[small][bodyfont=5pt] \input tufte \startsmallformula \hbox{small and boring: } e = mc^2 \stopsmallformula \input tufte \stoptext When ok i can incorporate the bodyfont key Hans
