(It is to be called via another command.) It seems that `define-derived-mode' always sets the mode as `interactive'. I tried to define my mode using (define-derived-mode my--mode special-mode "My mode") and then did M-: (symbol-plist 'my--mode) expecting an `interactive-form' entry on the plist - but it was not there. (I wanted to remove it from the list so that it can't be called with M-x.) What's going on? Is it possible to define a (derived) major mode so that it can't be called interactively?
