I use chinese to input normal text in latex .
And in math mode we almost use english .

I use `shift' to switch between chinese and english .

So now I use shift too frequently , my shift key is not sensitive .

How to make emacs switch  automatically ?

When  in math mode ,  emacs switchs to english .
When  in normal text ,emacs switchs to chinese.

Can here anyone  give some instructions of doing this ?

I know there is function `texmathp' in auctex which determines if point is
inside latex mode .

Thanks

Write a function, that does the job. In this case switching
between english (current-input-method = nil) and your preferred
method, depending on the circumstances.

(defun LaTeX-dynamic-input-method-toggle-maybe ()
  (when (or (and current-input-method
                 (texmathp))
            (and (not current-input-method)
                 (not (texmathp))))
    (toggle-input-method)))

Define a minor-mode, so this behaviour can be conviniently
enabled/disabled. The minor-mode puts the above function on the
`post-command-hook', so that the above function gets called
everytime you do something (e.g. move point).

(define-minor-mode LaTeX-dynamic-input-method
  "Dynamically disable input-method in math-mode."
  nil nil nil
  (if LaTeX-dynamic-input-method
      (add-hook 'post-command-hook 'LaTeX-dynamic-input-method-toggle-
maybe nil t)
    (remove-hook 'post-command-hook 'LaTeX-dynamic-input-method-toggle-
maybe t)))

Enable the mode in LaTeX-mode.
(add-hook 'LaTeX-mode-hook 'LaTeX-dynamic-input-method)

Sorry, I suck at explaining stuff, especially my own.

Thanks very much !

Now how to simulate `shift' key in elisp just like I stroke it ?

How to know the current input state ?

Below is my thought :
I use scim .  When I input chinese , It  use `space' to choose the first
character after I input `chinese pinyin'.
So if we simulate `k ' (k and a space) , when the character before point is
not `k '  I can know the current state is chinese. (This relate to character
code problem)

Is there any other better method?

Thanks again.
