Hi, I just jumbled upon this question on tex stackexchange : https://tex.stackexchange.com/questions/715799/context-switching-font-for-bo... Using the style key as suggested in the accepted answer works, but I've had a look in to this, and I don't understand why the original code does not work. I've also tried to find a solution using textcommand instead of command, but that makes no difference. Only one setting will be accepted. As soon as both, titles and subjects, are changed only the first change will be accepted. Is this a bug, or am I missing something? Best, Denis %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Original MWE \define[2]\mytitle{% \switchtobodyfont[chorus]% #2 } \define[2]\mysubject{% \switchtobodyfont[chorus]% #2 } \setuphead[title][command=\mytitle] \setuphead[subject][command=\mysubject] \starttext \title{In Zapf Chancery} \subject{Apparently the default font.
