Does anybody know how to configure Emacs or Auctex such that when you insert an environment for example with C-c C-e equation RET? Avoid having to type RET for (Optional) What label? question? Or completely stop being asked for any kind of label?



The insertion of environment labels is controlled by the LaTeX-label-alist variable. If you don't want environment labels, theoretically you would need to make that variable nil:

(setq LaTeX-label-alist nil)

Unfortunately, this setting will be overridden for the environments provided by the amsmath package and the longtable environment.

A much more coarse solution would be to redefine the LaTeX-label function to do nothing. Add the following to your .emacs

(eval-after-load "latex"
     (defun LaTeX-label (env))))

So you'll never be prompted for labels after inserting an environment with C-c C-e or a section with C-c C-s. You'll be able to manually add labels with C-c C-m label RET as usual.
