问题 I used the following jQuery example which works like a charm. However it appends the results.

问题 I am trying to replace a character - say ; - with a new line using replace-string and/or replace-regexp in Emacs. I have tried the following commands: M-x replace-string RET ; RET \n This will replace ; with 2 characters: \n .

Is there any other way to do it? Thanks. 回答1: M-x replace-string RET ; RET C-q C-j
