Re: [AUCTeX] adding function to LaTeX-math-list

[Michael Massmann]

Dear Ivan,

many thanks for your kind response. Your solution works perfectly. I had
indeed tried to modify the existing LaTeX-math-cal function but didn't
realise that the (intercative) statement was necessary and I must have
deleted it in the process of simplifying that function a little (it
contains a further if statement, if I remember correctly).

Can you recommend a consise Elisp tutorial that explains all of its main
features, without going into as much detail as the manual? That would be
handy in the future, I think.

Thanks again for your help!

Regards,
Michael
