May I ask how to insert citations in that style into a message buffer? I
have been wondering about that before since it pops up on this list
rather frequently. So far I only know about message-mark-inserted-region
which generally suits my purposes very well but I'm still curious to
learn about „that other way“.

Sorry for hijacking this thread and Thanks for any hints,
