Hello list! I was reading the following: https://wiki.contextgarden.net/Style_Alternatives I wanted to figure out how to make a simple module. However, there's a point in the example below which I don't understand % macros=mkvi \startmodule[look] \unprotect \writestatus{loading}{ConTeXt User Module / look} %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \installnamespace {look} \installcommandhandler \????look {look} \????look \appendtoks \setuevalue{\currentlook}{\do_look{\currentlook}} \to \everydefinelook \unexpanded\def\do_look#id{% \edef\currentlook{#id}% \dosingleempty\do_do_look% } \def\do_do_look[#parms]#content{% \begingroup \iffirstargument\setupcurrentlook[#parms]\fi %This handles style and color \uselookstyleandcolor\c!style\c!color% #content% \endgroup% } \protect %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \stopmodule What have I to do if, instead of "color" or "style", I want to use another keyword, as "dummy" and get its value? Something like \definelook[lol][dummy = blabla] \lol{words} %e.g. words \emph{blabla} or something similar so "lol" is a word, a number or whatever. I've read something about command handlers, but I'm having a hard time trying to understand them. Thank you in advance!
