Instead it marks the key as unbound, thus hiding any potential corresponding binding in parent keymaps. Emacs does not provide a "remove binding" operation on keymaps. > (key-binding [?a]) > => self-insert-command Here the binding was not found in the buffer-local map but in the global map instead.
