Again, I'm finding the stack of things involved in the input method getting invoked rather difficult to follow, but it feels like Quail doesn't actually look backwards in the buffer and thus could care less that I inserted a particular character there. That said, I don't truly get how all this works yet, there's no documentation and a heap of twisty code involved. Perry
