Just some thoughts about this... I was more thinking about the repeat feature of Vi/Vim (the '.' command) than the redo one. Two other ways of doing the undo/redo: 1/ Save the actions using a data type that we can inverse. Example in Ruby syntax a = Action.add_labels(:foo, :bar) a.apply # actually do the job a.invert # equals to Action.remove_labels(:foo, :bar) 2/ Save the state (has to be defined) at each action. This solution would be limited to actions where the state is manageable.
