I have to admit that I still don't get _why_ this is > happening. Where do you expect `with-current-buffer` (or `set-buffer` for that matter) to put the position of `point`? Remember that between execution of two commands, there can be a *lot* of other code that will be running (via redisplay, jit-lock, post/pre-command-hook, you name it). So while you want to go back to where *you* were, Emacs doesn't really know what you mean by that. Stefan
