Slime remaps several keys I like to use and have set in global-set-key.
I'd like to avoid directly editing slime.el.
What's the routine to override keys in a given mode?
Update:
In your .emacs, set the mode-map directly:
(define-key slime-mode-map "\M-n" 'next-line)
(define-key slime-mode-map "\M-p" 'previous-line)
It's not too easy to redefine a key for a mode since it can provide several keymaps. And there can be many modes that grab my favorite keys.
I solved it this way: I defined a minor mode that doesn't do anything except it has it's own keymap. I put some keys there i want to be really global.
;; my minor mode for really global keybindings
(defvar my-keys-minor-mode-map (make-keymap) "my-keys-minor-mode keymap.")
(define-minor-mode my-keys-minor-mode
"My minor mode for global keybindings."
:init-value t :lighter "" :keymap 'my-keys-minor-mode-map)
(defun my-minibuffer-setup-hook ()
(my-keys-minor-mode 0))
(add-hook 'minibuffer-setup-hook 'my-minibuffer-setup-hook)
(my-keys-minor-mode 1)
;; for example
(define-key my-keys-minor-mode-map (kbd "C-a") 'mark-whole-buffer)

What is the proper way to override a keybinding for a major mode so it only affects the buffer-local keymap? I thought I could use local-set-key or make-local-variable, but my attempts there affect the keymaps globally (shown below).
Is it necessary to copy the map, as done below, or create a minor mode with a different keymap? It would be nice to be able to make it a local variable if possible.
For example, say I want to have original bound to C-c C-c in the global emacs-lisp-mode-map but after calling jump-to-other-buffer I want C-c C-c to be bound to local-version only in that buffer.
(defun original ()
(interactive)
(message "original"))
(defun local-version ()
(interactive)
(message "local binding"))
;; open new buffer in emacs-lisp mode and set a local key
(defun jump-to-other-buffer ()
(interactive)
(with-current-buffer (get-buffer-create "*test1*")
(emacs-lisp-mode)
;; These change bindings in all elisp buffers
;; (make-local-variable 'emacs-lisp-mode-map)
;; (define-key emacs-lisp-mode-map (kbd "C-c C-c") 'local-version)
;; (local-set-key (kbd "C-c C-c") 'local-version)
(let ((overriding-local-map (copy-keymap emacs-lisp-mode-map)))
(define-key overriding-local-map (kbd "C-c C-c") 'local-version)
(use-local-map overriding-local-map))
(pop-to-buffer (current-buffer))))
;; default binding in elisp buffers
(define-key emacs-lisp-mode-map (kbd "C-c C-c") 'original)
I have an emacs shortcut set up like so:
;; Adding the key mappings to minor mode.
(defvar my-keys-minor-mode-map (make-keymap) "my-keys-minor-mode keymap.")
;; Cancel with one press of escape instead of three.
(define-key my-keys-minor-mode-map (kbd "<escape>") 'keyboard-quit)
(my-keys-minor-mode 1)
(defconst my-minor-mode-alist (list (cons 'my-keys-minor-mode
my-keys-minor-mode-map)))
(setf emulation-mode-map-alists '(my-minor-mode-alist))
This works great to override a shortcut in a truly global way, superseding all other minor modes. However I need a way to have a shortcut behave differently in different minor modes. For example I would like the escape key to run helm-keyboard-quit when helm is running bu run keyboard-quit otherwise. Doing so like:
(eval-after-load "helm"
'(progn
(define-key helm-map (kbd "<escape>") 'helm-keyboard-quit)))
won't work because the global escape shortcut will override it. Is there a way to do this?
Why not use a simple lambda. Something like this (untested):
(global-set-key (kbd "<escape>")
(lambda()
(interactive)
(if helm-mode (helm-keyboard-quit)
(keyboard-quit))))
When using ergo emacs, for some reason M-l and M-j (forward-char and backward-char respectively) don't work properly in the minibuffer (with ido mode).
I've tried setting the ido-completion-map with the following:
(add-hook 'ido-setup-hook
(lambda ()
(define-key ido-completion-map (kbd "M-k") 'ido-next-match)
(define-key ido-completion-map (kbd "M-i") 'ido-prev-match)
(define-key ido-completion-map (kbd "M-l") 'ido-next-match)
(define-key ido-completion-map (kbd "M-j") 'ido-prev-match)))
but these don't seem to stick.
I seem to be having a similar problem to this person: ido-mode binding masked by global-set-key but none of the solutions seems to work for me
Any help would be very appreciated
Kind regards
Nimai
Although the instructions at the outset of ido.el suggest using:
;; Customization
;; -------------
;;
;; Customize the Ido group to change the Ido functionality.
;;
;; To modify the keybindings, use the ido-setup-hook. For example:
;;(add-hook 'ido-setup-hook 'ido-my-keys)
;;
;;(defun ido-my-keys ()
;; "Add my keybindings for ido."
;; (define-key ido-completion-map " " 'ido-next-match)
;; )
I recently found that using the ido-common-completion-map had better luck when using a frame-switch function -- the original poster can substitute his / her own preferred keyboard shortcuts instead of m-tab and/or m-S-tab:
(add-hook 'ido-setup-hook 'ido-my-keys)
(defun ido-my-keys ()
"Add my keybindings for ido."
(define-key ido-common-completion-map (kbd "<M-tab>") 'ido-next-match)
(define-key ido-common-completion-map (kbd "<M-S-tab>") 'ido-prev-match) )
I have met the save problem, i'm using Emacs 24.4 with ergoemacs-mode-5.14.7.3 (i don't use the latest version of ergoemacs because it has the speed issue. See: github issue). After a lot of searching, i finally find this github commit, and get it work by adding below code to my emacs init file:
after enable ergoemacs-mode:
(when ido-mode
(global-set-key [remap ido-magic-forward-char] 'ido-next-match)
(global-set-key [remap ido-magic-backward-char] 'ido-prev-match))
Hope it helps, thanks!
Even after following all that was given in
Globally override key binding in Emacs
I still couldn't get it to work.
I bound M-o to other-window in my global key map like this:
(defvar my-keys-minor-mode-map (make-keymap) "my-keys-minor-mode keymap.")
(define-key my-keys-minor-mode-map "\M-o" 'other-window)
(define-minor-mode my-keys-minor-mode
"A minor mode so that my key settings override annoying major modes."
t " my-keys" 'my-keys-minor-mode-map)
(my-keys-minor-mode 1)
(defun my-minibuffer-setup-hook ()
(my-keys-minor-mode 0))
(add-hook 'minibuffer-setup-hook 'my-minibuffer-setup-hook)
;; Maintain the above keymap even after loading a new library
(defadvice load (after give-my-keybindings-priority)
"Try to ensure that my keybindings always have priority."
(if (not (eq (car (car minor-mode-map-alist)) 'my-keys-minor-mode))
(let ((mykeys (assq 'my-keys-minor-mode minor-mode-map-alist)))
(assq-delete-all 'my-keys-minor-mode minor-mode-map-alist)
(add-to-list 'minor-mode-map-alist mykeys))))
(ad-activate 'load)
but dired mode overrides this and remaps it to dired-omit-mode.
What am I missing ?
Your minor mode is defined to be buffer-local. You can Define it to be global, like this:
(define-minor-mode my-keys-minor-mode
"A minor mode so that my key settings override annoying major modes."
:global t
:lighter " my-keys")
But then your my-minibuffer-setup-hook will turn it off globally as well. Also if it's global and you basically always have it ON, you might prefer to not provide the :lighter " my-keys", so your mode-line isn't filled unnecessarily.
In particular, when I load dired-x, it sets M-o to toggle the omit minor mode. I use M-o for other-window, so I would like to change the key that dired-x binds to something else. I've attempted setting the key after the mode loads like this:
(add-hook 'dired-mode-hook
(lambda ()
(dired-omit-mode 1)
(global-set-key (kbd "M-o") 'other-window)
))
but to no avail.
Slightly better than adding another copy of your custom global binding to the local mode map, would be removing the local binding so that it no longer shadows the global binding. You might also give that function a new key before you do this.
(eval-after-load "dired-x"
'(progn
;; Add an alternative local binding for the command
;; bound to M-o
(define-key dired-mode-map (kbd "C-c o")
(lookup-key dired-mode-map (kbd "M-o")))
;; Unbind M-o from the local keymap
(define-key dired-mode-map (kbd "M-o") nil)))
The dired-mode bindings "shadow" the global ones so your "global-set-key" isn't helping. What you want to do is override the dired-mode binding:
(add-hook 'dired-mode-hook
(lambda ()
(dired-omit-mode 1)
(define-key dired-mode-map (kbd "M-o") 'other-window)
))
