Hello, I am using the tcolorbox latex package which doesn't use the usual '\label' command. Instead, one has to specify a label in key-val form as in
\begin{thm}[label={thm:1}]{}{} $1=2/2$ \end{thm} Is there a way to have reftex/auctex work with this variation? What I mean is this 1) reftex keeps track of these as labels and when I want to reference this theorem, 'C-c )' will show this to me. (Until today, this was working fine, but now reftex doesn't recognize this form of a label. I have no idea what happened, what's changed. ) 2) auctex/reftex enters a label in this key-val form when I do 'C-c ('. 3) the "renumber simple labels" function works with such references. Thanks for your help, Máté
