## 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 with 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.

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).

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.
