Disable C-Tab in magit mode

Question

I use C-Tab and C-Shift-Tab to navigate buffer as I would do in a browser. Unfortunately, in magit-mode (which I call using magit-status), the key is bound to some diff expansion. The means that I can't switch buffers the ways I would like to as soon as one buffer is in magit-mode. I tried removing the binding using

(define-key magit-mode-map
    (kbd "C-<Tab>") nil)

However, this does not seem to have any effect. Any ideas on how to fix this?

Edit:

Regarding my settings: I have a .emacs.d/buffers.el which has a line defining the key binding: (global-set-key [C-tab] 'next-buffer).

I am using use-package to load magit:

(use-package magit
  :ensure t
  :config
  (define-key magit-mode-map (kbd "C-<Tab>") nil)
  (with-eval-after-load 'magit-mode
    (define-key magit-mode-map (kbd "<C-Tab>") nil))
  (setq magit-display-buffer-function
        (lambda (buffer)
          (display-buffer buffer '(display-buffer-same-window)))))

I added the suggestion by Konstantin Morenko, but C-Tab still does not work properly.

Works for me. Would you care to add some details about how you set things up? — npostavs, Jul 28 '16 at 17:18

Does it work if you use `(kbd "C-")`? Note the lower case t. — npostavs, Jul 29 '16 at 11:04

According to Remove key binding in magit-status-mode use in init.el

(with-eval-after-load 'magit-mode
  (define-key magit-mode-map (kbd "<C-Tab>") nil))

The (with-eval-after-load FILE &opt BODY) executes BODY after the FILE is loaded, so, it will rebind keys only after the keybind in magit-mode will be created.

Edit:

From the documentation of bind-key.el from use-package

;; If you have lots of keybindings set in your .emacs file, it can be hard to
;; know which ones you haven't set yet, and which may now be overriding some
;; new default in a new emacs version.  This module aims to solve that
;; problem.
;;
;; Bind keys as follows in your .emacs:
;;
;;   (require 'bind-key)
;;
;;   (bind-key "C-c x" 'my-ctrl-c-x-command)
;;
;; If you want the keybinding to override all minor modes that may also bind
;; the same key, use the `bind-key*' form:
;;
;;   (bind-key* "<C-return>" 'other-window)

So, use in your buffers.el

(require 'bind-key)
(bind-key "<C-Tab>" 'next-buffer)

It did not work on my setup (Emacs on Windows) until I converted the first letter of "Tab" to lower case: `(kbd "") ` — kotchwane, May 13 '20 at 13:09
