May I ask why the standard key-binding of join-line (M-^) is not
sufficient for you?

Thanks    H. Dieter Wilhelm

I don't need the original C-j keybinding, the "M-^" needs to press 3 keys at same time, so I want to rebind the C-j to join-line. I am just wondering how to rebind the key or how can I find the hook.

After opening the Emacs, I type  (local-set-key (kbd "C-j") 'join-line)  and then Cx Ce, It works!!
But it dosen't work at .emacs,  can you help, I guess I need to find the last setup's hook.

Thanks

Alex Wei

Does adding anything else work?
Maybe you have an old .emacs.elc in the directory that gets loaded first?

Have you tried (global-set-key)?  Maybe local-set-key works only in
the *scratch* buffer at start-up?  Sorry I'm not sure.

Hi 

Thanks for your reply, I don't have .emacs.elc in my home direcory, I am using the emacs-22.1.
There's only one .emacs there, not sure why I can't rebind the C-j key to join-line.

Hi 

Thanks for your replay, I still can't figure out why yet, both global-set-key and local-set-key can't rebind the C-j keys to join-line, only local-set-key works by issueing C-x C-e after Emacs started.

I guess I need to find the last setup's hook.

Hi all

I've figured out how to secure binding my keys :D , I found two hooks that will guarantee my key-bindings will not be overrided.

(defun my-key-binding ()
  "Customize my key bindings after Emacs startup."
  (interactive)
  ;; Key bindings                                                                
  (local-set-key (kbd "<RET>") 'newline-and-indent)
  (local-set-key (kbd "C-.") 'set-mark-command)
  (local-set-key (kbd "C--") 'kill-whole-line)
  (local-set-key (kbd "C-=") 'copy-whole-line)
  (local-set-key (kbd "C-o") 'open-newline)
  (local-set-key (kbd "C-j") 'join-line)
 )

(add-hook 'emacs-startup-hook 'my-key-binding)
(add-hook 'change-major-mode-hook 'my-key-binding)

Thanks anyway!

This is really bad. Do you see why? If not, you will surely find out
soon. Your key bindings take effect in places that you don't want them
to. For example, RET is a useful key in the minibuffer, it's a shame to
rebind it there.

Why not the standard binding (C-SPC)?

>   (local-set-key (kbd "C--") 'kill-whole-line)

the same here C-S-backspace? (OK, I answer it myself: One needs three
keys.)  But you are restricting yourself to M-- and C-u- for negative
prefix arguments.

Yes, this is a function I'm also missing badly in Emacs.

What is open-newline, something like C-e RET?

>   (local-set-key (kbd "C-j") 'join-line)

As I said M-^ is not so bad either ;-)

> (add-hook 'emacs-startup-hook 'my-key-binding)

Sorry I do not know these hooks, but wouldn't for example:

(global-set-key "\C-o" 'open-newline)

in your .emacs have the same effect without adding hooks?

You are very welcome.

Hi H. Dieter Wilhelm

Thanks for disgussing, your understandings are almost right.

for
C-o  -- Yes, just  C-e <RET>, the same effect as Vim's  o command
C--   -- Kill whole line, same as  C-a C-k C-k, kill whole line along with the last carriage return.
C-=  -- Yes, I define it as copy whole line, the same effect as Vim's  yy command
C-.  -- Why binding this to set-mark-command, and not C-SPC, because It was defined by Windows to activate IME. 

Why hook it up? Because other scripts override my key bindings after Emacs startup,  .emacs was executed the first.
Appending my codes for your reference.

(defun copy-whole-line ()
  "copy line"
  (interactive)
  (setq end-pos (if (< (line-end-position) (point-max)) (+ 1 (line-end-position)) (point-max)))
  (copy-region-as-kill (line-beginning-position) end-pos)
  (message "line copied.")
)

(defun kill-whole-line ()
  "cut line"
  (interactive)
  (setq end-pos (if (< (line-end-position) (point-max)) (+ 1 (line-end-position)) (point-max)))
  (kill-region (line-beginning-position) end-pos)
)

(defun open-newline ()
  "open newline below and place the cursor at newline."
  (interactive)
  (goto-char (line-end-position))
  (newline-and-indent)  
)

Best Regards

What does `C-h v initial-major-mode' say?  What major mode do you do
most of your editing in?
