25 ;;; Commentary:
26
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.
37 ;;
38 ;; (define-key isearch-mode-map "\C-k" 'isearch-edit-string)
