I know that the default mode of Auctex is that prompting c-c c-e equation RET is supposed to ask me to prompt a label, unless I modify purposely the reftex-plug-into-AUCTeX value.
I find myself in a situation where, after installing the last version of aquamacs (on a new config), I am not asked anymore to prompt a label, which is assigned by default to some eq:N value.
I'd like to have this very convenient prompting feature back, any idea where I should look for ?
