Regexp replacement

Regexp replacement

[Jim Dai]

I would like to delete \redtext{long text} with "long text" being kept.
I have any instances in a file, with "long text" varying that may include
other latex symbols like _ $. (assume there are not any {} pairs inside the
text.

How can I use regexp replacement to achieve the desired changes?
Thanks.

M-x query-replace-regexp RET \\redtext{\([^}]*\)} RET \1 RET

Hmm, I missed \( \) and \1 combination in my own try.

How can create a key-binding such as C-c C-r in LaTeX mode? Thanks.

(define-key LaTeX-mode-map (kbd "C-c C-r") 'beep)

Or probably (if in .emacs) rather

(add-hook 'LaTeX-mode-hook
  (lambda nil
    (define-key ...

Such binding should be reserved for major modes.  User bindings should
be of the form `C-c <letter>', see (info "(emacs)Keymaps").

Or use `local-set-key' if one does not want to think about the name of
the local keymap.

Once again, thanks for the solution. It basically solved my problem.

Two more questions:
1) 
I wonder if there is an easy improvement on the current method so that I
have nested {} inside the text.
E.g. I would like to replace \redtext{some formula $\frac{a}{b}$} to
Some formula $\frac{a}{b}$.

2)  I did not make it clear when I asked a key binding question. How can I
bind the entire key strokes M-x query-replace-regexp RET
\\redtext{\([^}]*\)} RET \1 RET into an emacs key?

This key binding is to  be used in LaTeX mode.

Thanks.

Please don't toppost with fullquote below.  If you refer to anything,
it is a pain to dig the context up from the bottom, and try to guess
what you actually might be referring to.

Please cut away anything not relevant to your reply, and put your
reply below the stuff you are replying to.

No.  You need to revert to Elisp in this case and parse the argument
using something like forward-sexp.

Use C-x Esc Esc after the command in order to get a versino in Elisp.

Got it. Very much appreciate your helpful answers.
