Xcode inserts an invisible character whenever I press Ctrl+X, Ctrl+S (was trying to save the code but then realised that I am not using Emacs and should use command+S instead, and went back to delete the festy character.) Deleting something that is invisible is not fun, so.
Is there a way I can disable this "feature"? And by that I mean make Xcode stop inserting the character and essentially does nothing when I press the key combination. I am not looking for a full Emacs key binding setting for Xcode.
