27 ;; This program is extension of isearch.el to support multi-lingal
|
|
|
28 ;; incremental search with front-end input method.
|
|
|
29 ;;
|
|
|
30 ;; If you want to use this program, simply put C-\ or C-o or C-[ when
|
|
|
31 ;; doing incremental search, and you can input search words with
|
|
|
32 ;; inputting method.
|
|
|
33 ;;
|
|
|
34 ;; For backward compatibility with mule-1.x, you can also use C-k, but
|
|
|
35 ;; isearch-edit-string may be more suitable for this use. If you
|
|
|
36 ;; think so, put the following code in your .emacs.
