I am trying to create a new key-bind that will work fine in all modes except for one, where it conflicts with another. For example:

(global-set-key (kbd "<C-S-down>") 'move-line-down)

Is there a simple way (without setting it for specific local modes) to make it global excluding a specific mode?

    Is the conflicting mode a major or minor mode? In the latter case, you could put your key binding in a minor mode and ensure that `minor-mode-map-alist` gives the correct precedence. – François Févotte Jan 06 '13 at 18:15

    Global key bindings *cannot* clobber major or minor mode keybindings. The latter take precedence (minor over major over global). I would avoid referring to a binding as 'global' (and referencing `global-set-key`) if you are not explicitly referring to the global keymap, because it will just confuse matters. Do you actually want to create a binding that takes precedence over all major and minor mode maps (save for one)? – phils Jan 06 '13 at 20:29
  • @Francesco The conflicting key bind is in a major mode. – scottyaz Jan 07 '13 at 02:09

You could add a function to after-change-major-mode-hook that would set the key in the current local keymap, except for the specific modes you would like to avoid.

If you want to exclude one specific mode, you can do the following: 

(global-set-key (kbd "<C-S-down>") 'move-line-down)

to make it globally available, and

(define-key KEYMAP (kbd "<C-S-down>") nil)

to exclude one mode where KEYMAP is the name name of the mode, followed by "mode-map" (e.g. ess-mode-map). You could also bind the original thing to the key instead of nil.
