Selecting an Input Method
=========================

`C-\'
     Enable or disable use of the selected input method.

`C-x <RET> C-\ METHOD <RET>'
     Select a new input method for the current buffer.

`C-h I METHOD <RET>'
`C-h C-\ METHOD <RET>'
     Describe the input method METHOD (`describe-input-method').  By
     default, it describes the current input method (if any).  This
     description should give you the full details of how to use any
     particular input method.

`M-x list-input-methods'
     Display a list of all the supported input methods.

   To choose an input method for the current buffer, use `C-x <RET>
C-\' (`set-input-method').  This command reads the input method name
from the minibuffer; the name normally starts with the language
environment that it is meant to be used with.  The variable
`current-input-method' records which input method is selected.

   Input methods use various sequences of ASCII characters to stand for
non-ASCII characters.  Sometimes it is useful to turn off the input
method temporarily.  To do this, type `C-\' (`toggle-input-method').
To reenable the input method, type `C-\' again.

   If you type `C-\' and you have not yet selected an input method, it
prompts for you to specify one.  This has the same effect as using `C-x
<RET> C-\' to specify an input method.

   When invoked with a numeric argument, as in `C-u C-\',
`toggle-input-method' always prompts you for an input method,
suggesting the most recently selected one as the default.

   Selecting a language environment specifies a default input method for
use in various buffers.  When you have a default input method, you can
select it in the current buffer by typing `C-\'.  The variable
`default-input-method' specifies the default input method (`nil' means
there is none).

   In some language environments, which support several different input
methods, you might want to use an input method different from the
default chosen by `set-language-environment'.  You can instruct Emacs
to select a different default input method for a certain language
environment, if you wish, by using `set-language-environment-hook'
(Note: set-language-environment-hook.).  For
example:

     (defun my-chinese-setup ()
       "Set up my private Chinese environment."
       (if (equal current-language-environment "Chinese-GB")
           (setq default-input-method "chinese-tonepy")))
     (add-hook 'set-language-environment-hook 'my-chinese-setup)

This sets the default input method to be `chinese-tonepy' whenever you
choose a Chinese-GB language environment.

   Some input methods for alphabetic scripts work by (in effect)
remapping the keyboard to emulate various keyboard layouts commonly used
for those scripts.  How to do this remapping properly depends on your
actual keyboard layout.  To specify which layout your keyboard has, use
the command `M-x quail-set-keyboard-layout'.

   To display a list of all the supported input methods, type `M-x
list-input-methods'.  The list gives information about each input
method, including the string that stands for it in the mode line.
