That's because "modifying" is the wrong way to think about it. That section should start by telling the user that most likely what they really want to do is something else (i.e. get a similar list structure with some differences). > I would certainly have considered that if I had known that setq was > linking the lists :) Clearly, "linking the lists" means something to you, but it means nothing to me, so the manual can't really say something like that.
