Emacs 24.5, turn on CUA mode.
My binding:
(global-set-key (kbd "M-x") 'helm-M-x)
I want paste(yank) by C-v in minibuffer in 2 cases:
M-x and then paste(C-v) some text
I-search (C-f) and then paste(C-v) some text
Is this a possible in CUA mode?
I found a solution from: http://tahirhassan.blogspot.kr/2014/01/emacs-cua-mode-and-isearch.html
(define-key isearch-mode-map (kbd "C-v") 'isearch-yank-kill)
It works for me.
M-x C-v works fine, with emacs -Q (no init file).
C-s C-v does not - it seems that cua-mode does not affect Isearch - just use C-y instead of C-v. If you want a change in that regard (i.e., an improvement for cua-mode with Isearch), consider filing an Emacs enhancement request: M-x report-emacs-bug.
If the problem is introduced by using Helm (which it seems to be), consider filing a Helm bug report or asking Helm support. (But maybe someone here can tell you how to handle that.)

I've been working with VIM for decades, and I've become quite proficient in it. I was however sort-of... seduced by Emacs's org-mode, and in order to try it, I installed Emacs and Evil.
Evil satisfies most of my VIM-related muscle memory, so I proceeded with my testing of org-mode - and met my first issue: when I spawn Emacs in its own window (i.e. emacs plan.org) then the TAB key works, opening and closing my plan's sections just fine. However, TAB does nothing when I use Emacs in text mode (i.e inside my XTerms, via "emacs -nw plan.org"). And that's the state that I am mostly interested in, since I usually work from inside screen/tmux over SSH connections.
If it's a conflict with Evil-mode, I don't understand why - I am unaware of any TAB functionality in VIM's normal mode (which is what we're in when opening/closing org-mode sections).
Any Emacs-guru out there with a suggestion on why this happens?
Try
(setq evil-want-C-i-jump nil)
in your ~/.emacs before
(require 'evil)
Evil has, in evil-maps.el
(when evil-want-C-i-jump
(define-key evil-motion-state-map (kbd "C-i") 'evil-jump-forward))
That should give you org-mode Tab functionality back
I have almost no experience with terminals. However, I know that TAB is equivalent to C-i. Maybe that one would go through the terminal? If that works, you could add some key bindings for every TAB operation?
Try maybe C-h k TAB as well to see if TAB if sent on the wire.
(define-key evil-normal-state-map (kbd "M-i") 'evil-jump-forward)
(define-key evil-normal-state-map (kbd "M-o") 'evil-jump-backward)
I bind the function to other keys, so it's also work.
I am trying to bind M-<up> and M-<down> to scroll-down-line and scroll-up-line respectively as indicated here: https://stackoverflow.com/a/16229080/562139.
This is what I have in my .emacs:
;; Key bindings
(global-set-key (kbd "M-g") 'goto-line)
;; Scroll line by line
(global-set-key (kbd "M-<down>") 'scroll-up-line)
(global-set-key (kbd "M-<up>") 'scroll-down-line)
Problem:
The scroll key bindings are not taking effect, while the one for goto-line does.
When I run M-x scroll-down-line however, emacs prompts me and says
"you can run the command with <M-down>"
Note:
When I run global-set-key (kbd "M-<down>") 'scroll-up-line) or (global-set-key (kbd "M-<up>") 'scroll-down-line) directly in the mini-buffer, the bindings take effect! However, I seem to have noticed through the corner of my eye when I do the latter, that pressing M-<up> actually sends something like ESC ESC-<up>.
I'm foxed. What gives?
Note: I am running emacs 24.3 in a terminal (via iTerm on OSX with Option key mapped to ESC+) over SSH to a RHEL5 virtual machine.)
Update
I followed the suggestion in this answer and found that pressing M-<up> results in something completely different:
ESC <up> (translated from ESC M-[ A) runs the command
scroll-down-line, which is an interactive compiled Lisp function.
It is bound to <M-up>, ESC <up>.
(scroll-down-line &optional ARG)
I'm going to try binding that key sequence to the function and check the result.
Try starting Emacs without your init file: emacs -Q, and see if you can reproduce the problem.
I do not see the problem, with Emacs 24.3 in terminal mode.
What you saw briefly was probably ESC <up>, which is equivalent to M-<up>.
Did you perhaps mean to type "When I run M-x scroll-up-line (instead of down)?
I suspect that you are in some mode that gives a local binding or a minor-mode binding to these keys, which overrides the global binding. To test that, try in a buffer that is in fundamental mode. If that is the case, then to override that overriding you will need to also bind the keys in that mode's keymap.
If you cannot repro the problem starting from emacs -Q then bisect your init file (~/.emacs) recursively until you find the culprit code.
Seems key got lost in translation.
Planted a forward-paragraph at openSuse that way:
(global-set-key [(meta down)] 'forward-paragraph)
I'd like to map a command in emacs to a key-binding. I want the command Control-l to have the same effect as the command Alt-x goto-line followed by a return (since that command first needs a return to be invoked and then a line number).
I modified the init file as follows:
(define-key (M-x goto-line) '\C-l)
but that didn't work. The error was that define-key was being given more than 1 arguments.
Does anyone know how to reset key-bindings in emacs?
Thanks!
M-g g is the default shortcut for goto-line. You might want to try that.
To redefine C-l use:
(global-set-key (kbd "C-l") 'goto-line)
Easiest way to customize lots of keybindings is to install John Wiegley's bind-key module, which is a part of use-package Lisp package. Solution in your init.el:
(require 'bind-key)
(bind-key "C-l" 'goto-line)
Minor modes keys usually override global keys, so if you don't want such behavior, use function bind-key* instead. The package is on MELPA, if you don't know what is it, quickly learn about Emacs package management (should take you 2 minutes to set up MELPA as your repository).
The main problem with keybindings in Emacs is that minor modes keys often override your custom ones. In vanilla Emacs people workaround by creating a minor mode for your own keybindings. If you really wanna understand how Emacs keys work, read Key Bindings # Emacs Manual and Keymaps # Elisp Manual carefully.
I have set as (global-set-key (kbd "C-x g") 'goto-line). You can use that or (global-set-key (kbd "C-l") 'goto-line). I would personally do not touch the C-l key from its default behavior.
If you must use M-x define-key, use
(define-key global-map (kbd "C-l") 'goto-line). The 1st argument to define-key is a KEYMAP.
I've tried various version to no avail:
(global-set-key (kbd "C-<space>") 'tempo-complete-tag)
(global-set-key [C-space] 'tempo-complete-tag)
I'm using CUA mode and running Emacs on Ubuntu, version: GNU Emacs 23.1.50.1 (x86_64-pc-linux-gnu, GTK+ Version 2.18.0)
of 2009-09-27 on crested, modified by Debian
When I run tempo-complete-tag manually it tells me it is bound to C-space but C-space still runs cua-set-mark (or if CUA is disable, set-mark-command).
How can I rebind the C-space shortcut in Emacs to a command I decide?
C-h k (key) will tell you how Emacs refers to a given key (which is "C-SPC" in this instance). (global-set-key (kbd "C-SPC") 'tempo-complete-tag) will do what you want.
I always use the (kbd) function for key-bindings, as it allows you to refer to the key the same way it is typically written everywhere else.
Do keep in mind that C-SPC is a standard set-mark-command binding! Personally I'd pick something different :)
Also keep in mind that "global-set-key" will only do what you want, if your mode doesn't override it. I'm too lazy to load tempo to see if it does indeed override C-SPC, but it might well do so, in which case, you want to put this in your .emacs:
(add-hook 'tempo-mode-hook
(lambda ()
(local-set-key (kbd "C-SPC") 'tempo-complete-tag)
))
Alternative syntax for key binding is via vector:
(global-set-key [?\M-\ ] 'cycle-spacing)
(global-set-key [?\C-\ ] 'tempo-complete-tag)
I'm using Viper, and I want to change its C-c and C-g to the original emacs functions. I can rebind C-g with (define-key viper-vi-global-user-map "C-g" 'keyboard-quit), but how can I rebind C-c, since it's a prefix key?
Thanks!
It may make sense for you to run M-x viper-set-expert-level with an argument of 2 ("Master"). As the viper-mode documentation explains:
2 -- MASTER: C-c now has its standard
Emacs meaning in Vi command state, so
most Emacs commands can be used when
Viper is in Vi state.
As you master viper-mode, you're meant to increase your expert-level setting gradually over time, making more Emacs features available to you (or, as the Viper documentation puts it, "To use Emacs productively, you must reach level 3 or higher").
The original binding for C-c can be set with the following:
(define-key viper-vi-global-user-map (kbd "C-c") 'mode-specific-command-prefix)
The info page for this is Prefix Keys.
