Turn off global-flycheck-mode for org-mode?

Question

Given I'd like to keep using global-flycheck-mode, how can I make sure flycheck is automatically disabled when editing org-mode documents? Or maybe is just activate it for code blocks?

I found this discussion but I admit I don't know what to do with this information. :\

ORIGINAL QUESTION:

I'm trying to create a timestamp with both date and time in org-mode (without adding to agenda), and I read from the docs that I should be using this cord:

C-u C-c !

However, I get this in my minibuffer:

Seems like its waiting for more input. I'm an Emacs n00b so I'm not really sure what's happening here. I get the same behavior with

C-c !

Both versions with . work fine, though:

C-u C-c .

C-c .

What's happening here?

UPDATE: Thanks to suggestions from the comments below, I've determined Flycheck is doing something to screw this up: here's my flycheck config

(use-package flycheck
  :ensure t
  :init (global-flycheck-mode))
(add-hook 'after-init-hook #'global-flycheck-mode)

Where can I look to find if there is a colliding key binding?

Answer 1

I just did this by customizing flycheck-global-modes to be '(not org-mode).

In the customize interface, that was clicking except and repeat and adding an org-mode entry.

Answer 2

The prefix for flycheck commands is controlled by the flycheck-keymap-prefix variable. You can use customize to set this to your liking. If you don't use customize note that changing the value of flycheck-keymap-prefix is insufficient:

Changing this variable outside Customize does not have any effect. To change the keymap prefix from Lisp, you need to explicitly re-define the prefix key:

(define-key flycheck-mode-map flycheck-keymap-prefix nil)
(setq flycheck-keymap-prefix (kbd "C-c f"))
(define-key flycheck-mode-map flycheck-keymap-prefix
            flycheck-command-map)

Please note that Flycheck's manual documents the default keybindings. Changing this variable is at your own risk.
