It works for me and should work in any emacs 22. For interactive use,
i think C-q C-j is actually the only way to insert newlines.

If you are calling this function in elisp, you can use “\n”. But
literal line feed should also work...

so i'm not sure what might be your problem?

C-o   or   C-012 RET   also work for a query-replace.
C-o does not work by default for an incremental search.
The following code adds this shortcut to the incremental commands.

(define-key isearch-mode-map "\C-o"
           (lambda () (interactive)
             (isearch-process-search-char ?\n)))

Looks nifty -- but what does it do?

1: what's the purpose of defining C-o?

2: what does that function/lambda-expr actually *do*
   when it gets called>
(like, how does it get a newline inserted?)

Unfortunately:

| isearch-process-search-char is a compiled Lisp function in `isearch'.
| (isearch-process-search-char CHAR)

| Not documented.

Thanks,

It's shorter and perhaps easier to remember than C-q C-j.

If you follow the link to isearch, you'll see its definition, which has
this comment:

   ;; Append the char to the search string, update the message and 
re-search.

Using a newline character in the newstring in M-x replace-regexp

[Corey Foote]

Hi,



I've got one more quick question for you guys. The string
I'd like to use as the newstring in M-x replace-regexp contains a few newline
characters. Normally, I insert newlines by typing C-q C-j, but this doesn't
work when calling this function. How do you specify a newline character when
making a call to M-x replace-regexp?



Thanks!

If it doesn't work, then you have a buggy GNU Emacs. Upgrade!
