Modify latex commands in emacs

Modify latex commands in emacs

[michael]

Hi,

in auctex for emacs there is a command LaTeX-environment bound to C-c
C-e. If you call it, it asks you for an environment name, say test and
inserts then

\begin{test}

\end{test}

If you are in an latex-environment (possibly with some text in it) you
can easily modify the environment name by calling C-u C-c C-e = LaTeX-
environment with arg.

The analogous emacs command for inserting LaTeX (or TeX) commands is
TeX-insert-command (bound to C-c C-m in auctex).

Now my question is, if there is a way to modify an existing LaTeX-
command like in the environment case. Calling C-u C-c C-e seems not to
work.

Thanks
Michael
