That's the goal (and that's why I want to drop that current 'math undo works only on the containing text paragraph and makes the cursor always leave the inset - which is a pain to use). The question posed is merely an implementation detail. I'd guess 2. would feel more like a kludge but has less differing code initially, and 1. has at least initally more 'special' code which might or might not vanish once we have 'uniform' document iterators. When I think about it, I think, I lean towards 1 now. Andre'
