Hi, in my work I have a lot of formulas inkl. subformulas. Doing the examples at the wiki two questions came up: a) how to generate a table of formulas? b) what is the right/better way for subnumbering? a) I tried the example for generating a table of formulas from the wiki (http://wiki.contextgarden.net/Math/Display#List_of_Formulas) but instead of a list I get in the pdf a »no list method«. What do I missed here? b) I found two descriped ways how to create formula (sub-)numbering: 1) using \formulanumber and \subformulanumber (third example from http://wiki.contextgarden.net/Math/Display#The_Manual_Method). But context always reports here: ! Undefined control sequence. <argument> ...^{\vfrac {1}{2}} &\subformulanumber {b}\cr a^2 + b^2 &= c^2 &\... 2) using the \NR[..] like it is described on http://wiki.contextgarden.net/Multiline_equations#Working_with_equation_numb... and http://dl.contextgarden.net/myway/mathalign.pdf. This way compiles through. But which way is the future context way? In which way can I combine subnumbering and including to list some (not all) subformulas? Thanks for your help
