Remove key-mapping from org-mode

Question

I'm transitioning from VIM (using GNU Emacs 24.5.1). I want to move between "windows" using familiar keys i.e.

(global-set-key (kbd "C-k") 'windmove-up)
(global-set-key (kbd "C-j") 'windmove-down)
(global-set-key (kbd "C-h") 'windmove-left)
(global-set-key (kbd "C-l") 'windmove-right)

However in org-mode...

C-k runs the command org-kill-line, which is an interactive Lisp function in `org.el'.

It is bound to C-k.

(org-kill-line &optional ARG)

Kill line, to tags or end of line.

So I tried removing the org-kill-line mapping but I couldn't get it to work:

(eval-after-load "org"
   '(define-key org-mode-map [remap org-kill-line] nil))

Disclaimer: I've only been using emacs for 3 days so far.

Answer 1

Org-mode is built-in to Emacs 24.5.1, so there's no need to eval-after-load. with-eval-after-load is also preferred over eval-after-load.

Instead of trying to remap org-kill-line, why not just specify C-k?

(define-key org-mode-map (kbd "C-k") nil)

Also, there may be other modes that bind a common key like C-k. Instead, you can use C-c k. The C-(letter) keys, by convention, are reserved for user-specified bindings.
