Hi, as of actual need I summed up all kinds of formula numbering - some basics are working. You can find this list on my user talk page: http://wiki.contextgarden.net/User_talk:Zenlima As I also found a note in str-math.mkiv that it needs to be rewritten and the example syntax which leaded me to confusion in the past, I worked out a suggestion for a more intuitive syntax for formula numbering. In sum it ends with: All three commands: \NR \placeformula \formualanumber will share the same attributes: * sublevel (maybe better: formulalevel or just level?) to define and concrete the (sub-)level of the formula * listlabel (maybe textlabel? the numberlabel is still needed) to add a entry in the list of formulas * reference just a classic reference in order to link to it so that the syntax is more intuitive during the writing. Also. this way the commands: placesubformula placenamedformula placenamedsubformula startstopsubformulas subformulanumber will become needless. For the "why" and examples please look at: http://wiki.contextgarden.net/User_talk:Zenlima#Suggestion_for_new_syntax I hope you will find parts you like and feel free to add your opinion. :-) H.
