I read in evil wiki that I can change prefix keys such as C-c or C-x and so on to cc, cx, but I'm not experienced in Elisp and I tried a lot of variants but I can only define c as C-c but not a cc to C-c here is my evil.el file. What do I need to change in my evil.el or maybe in init.el to set cc as C-c and cx as C-x?

My evil.el file:

  (defvar evilPackages
  '(goto-chg
    evil-magit
    evil-matchit
    evil-escape))

(mapc #'(lambda (package)
    (unless (package-installed-p package)
      (package-install package)))
      evilPackages)

;; Undo-tree (as dependency of Evil)
(add-to-list 'load-path "~/.emacs.d/undo-tree")
(global-undo-tree-mode)

(use-package evil
  :ensure t
  :init
  (setq evil-want-C-u-scroll t)
  (setq evil-want-integration t) ;; This is optional since it's already set to t by default.
  (setq evil-want-keybinding nil)
  (require 'evil-magit)
  (require 'evil-matchit)
  (global-evil-matchit-mode 1)
 :config
  (evil-mode 1)
  (setq-default evil-escape-key-sequence "jk")
  (evil-escape-mode t))

(use-package evil-collection
  :after evil
  :ensure t
  :config
  (evil-collection-init))

Generally, I recommend to avoid key translating in emacs. I know it's common in vim but in emacs I think it's better to map your actions using modes and commands. That's because, in contrast to vim, everything in emacs is a command, so you don't really need to rely on key translation. You can check which command a key stroke is bound to with F1 k [key]. If you specify the reasons you need to do this we might help you with a better solution.

That said, the following code should do what you wish:

(defun my/c-c ()
  (interactive)
  (setq unread-command-events (listify-key-sequence (kbd "C-c"))))

(defun my/c-x ()
  (interactive)
  (setq unread-command-events (listify-key-sequence (kbd "C-x"))))

(evil-define-key 'normal global-map (kbd "cc") 'my/c-c)
(evil-define-key 'normal global-map (kbd "cx") 'my/c-x)

EDIT: If you want to rebind all ctrl keys, you could loop thourgh all the letters and map them like this:

(defun my/c-bind (letter)
  (let* ((l letter))
    (evil-define-key 'normal global-map (concat "c" letter)
      `(lambda () (interactive)
         (setq unread-command-events
               (listify-key-sequence (kbd (concat "C-" ',l))))))))

;; bind all looping from a to z
(defun my/c-bind-all()
  (let ((char 97))
    (while (< char 123)
      (my/c-bind (char-to-string char))
      (setq char (+ char 1)))))

(my/c-bind-all)

If you don't want every ctrl combination rebound, instead of using my/c-bind-all you could also bind keys individually with my/c-bind:

(my/c-bind "c") ;; bind 'cc' to ctrl-c
(my/c-bind "x") ;; bind 'cx' to ctrl-x

  • It's pretty good and works fine, but I expected something like cx where x can be any character, like super() in normal global-map, to avoid using C-c C-g C-x and so on, because its hard for hands to do it all day, my keys were rebind to caps_lock or to cmd or to any other key, anyway its really hard for hands.

    @om2c0de I edited my answer with a dynamic solution. Is that what you need?

  • Wow, you are like the elisp ninja!! Of course, this bounty will be yours, just last question - Does it really complex to watch for c(pressed) events like C-x f can be a cxf ?

  • Nah, I'm a elisp beginner. I just learn as I go, no rush. I don't understand your question. You mean cxf to be C-x C-f? Because cxf already should behave like C-x f

  • Yeah, so if i'm pressing "c" => c-x c-f as cxf, but if I just pressed once "c" => cxf as C-x f, Do you understand me? ;)
