Both make sense. For me, I'd rather not have to exit the theorem environment before entering a proof, or a corollary, or whatever. It would be possible to make this more flexible, though. There probably are cases, mostly involving lists, where you'd expect the list to be within the existing environment. E.g., lists within statements of theorems, or proofs, or what have you. One could have some kind of setting for different layouts that signalled whether they expected lists within them. Or maybe one could, by default, increase depth for lists within environments. Lots of possibilities. But any change would need discussion. > What is the trick that permits (for example) a Frame environment to > contain other environments without the need to "increase the depth" of > the inserted environment? > You can look at the beamer layout to see this, but it is a complete mess. You really don't want to do this. rh
