This is an edited AI response from keep org mode from hijacking C-# - Google Search
To keep Org Mode from hijacking C-# (or other keybindings, such as shift-cursor keys), you can customize how Org interacts with the keymap. The most common cause of this is Org trying to take control of keybindings for its own functionality (e.g., table editing or speed keys).
Here are the ways to stop this behavior, specifically targeting
org-disputed-keys.
The Recommended Fix: org-disputed-keys
Add this to your init.el or .emacs file to tell Org
mode not to hijack specific keys, allowing them to pass through to
your system or other modes:
(with-eval-after-load 'org
;; :kbd:`C-#` is the snippets/workspace multiplexer
(define-key org-mode-map [(control ?#)] (make-sparse-keymap))
(define-key org-mode-map [(control ?#) (control ?#)] #'org-table-rotate-recalc-marks)
;; :kbd:`C-c #` is the snippets/workspace multiplexer
(define-key org-mode-map [(control c) ?#] nil)
(define-key org-mode-map [(control c) (control ?#)] #'org-update-statistics-cookies)
)
Alternatively, if you are having issues with C-# being
used for org-table-rotate-recalc-marks(), you can
specifically rebind that to something else, or use nil to unbind
it entirely in org-mode-map.
Disabling Org Speed Keys
If C-# is being interpreted as a “speed key” at the beginning of a headline, you can disable the speed keys feature:
(setq org-use-speed-commands nil)
Handling Shift-Selection Conflicts
If the issue involves C-S-# or other shifted keys, you can
tell Org to yield to other modes (like CUA mode) by customizing the
org-replace-disputed-keys variable:
(setq org-replace-disputed-keys t)
;; Then define the mapping in org-disputed-keys if necessary
Direct Keybinding Removal
To ensure Org mode does not bind that key at all, you can explicitly remove it from the map:
(add-hook 'org-mode-hook
(lambda ()
(define-key org-mode-map (kbd "C-#") nil)))
After adding any of these, restart Emacs or evaluate the code (M-x eval-buffer) to apply the changes.
