Dear list, For TeX/LaTeX users there is the neat command line tool `texdef` with which you can show the definition of a macro. Here an example: $ texdef -t latex section \section: \long macro:->\@startsection {section}{1}{\z@ }{-3.5ex \@plus -1ex \@minus -.2ex}{2.3ex \@plus .2ex}{\normalfont \Large \bfseries } Is there something similar for ConTeXt? It is quite tedious to either grep the full source or setup an extra dummy document to use \show or \meaning. Cheers, Henri
