Remove local key binding in Dired

[Torben Knudsen]

I have the following which I find conveinent

;;; Window spliting
(global-set-key (kbd "M-3") 'split-window-horizontally) ; was digit-argument
(global-set-key (kbd "M-2") 'split-window-vertically) ; was digit-argument
(global-set-key (kbd "M-1") 'delete-other-windows) ; was digit-argument
(global-set-key (kbd "M-0") 'delete-window) ; was digit-argument
(global-set-key (kbd "M-o") 'other-window) ; was prefix

However, in dired

M-o runs the command dired-omit-mode

I can remove this "manually" by

local-unset-key M-o

in a dired buffer

but how can I do this in my .emacs?

Configure a Dired mode hook which sets M-o keybinding to nil in the
mode's local map:

(add-hook 'dired-mode-hook 'my-dired-mode-hook)

(defun my-dired-mode-hook ()
(define-key dired-mode-map (kbd "M-o") nil))

you might try the latest version of ergoemacs, which fixes this.
http://code.google.com/p/ergoemacs/

The code that fixes this is this:

(add-hook 'dired-mode-hook
(lambda ()
(define-key dired-mode-map (kbd "C-n") 'new-empty-buffer) ; was
dired-next-line
(define-key dired-mode-map (kbd "M-o") 'other-window) ; was dired-
omit-mode
(define-key dired-mode-map (kbd "M-s") 'isearch-forward) ; was
prefix in emacs 23.
))

WTF is ergoemacs??? :-o

Who really need this? And what is better in you own key bindings
compared to standard emacs? (except for your private preferences of
course.)

BTW:
- bad parens
- poor indent
- too long comments lines

Hi Marc,

There were numerous huge flame wars in the past couple of years
regarding this. Perhaps you are a new comer. :D

Here's some answer to your skeptism.

The Reason for ergoemacs is:

The reason that my elisp source code's formatting not always being
have 100% lisp convention is because partly lazy and partly consider
this formatting issue is a major myth that causes major harm to the
industry. Here's some essays about it:

• Fundamental Problems of Lisp
(see the section “Automatic, Uniform, Universal, Source Code
Display”)
http://xahlee.org/UnixResource_dir/writ/lisp_problems.html

• The Harm of Hard-wrapping Lines
http://xahlee.org/UnixResource_dir/writ/hard-wrap.html

• Tabs versus Spaces in Source Code
http://xahlee.org/UnixResource_dir/writ/tabs_vs_spaces.html

The following essays are on some feature that could've been:

• A Simple Lisp Code Formatter
http://xahlee.org/emacs/lisp_formatter.html

• A Text Editor Feature: Extend Selection By Semantic Unit

Thanks, this is exactly what I need. I have some small changes to
emacs key bindings. However I try to keep it at a minimum.

Thanks for the suggestion. I have some small changes to emacs key

bindings. However I try to keep it at a minimum.
