Please see `goto-line' - and why > not use goto-line? I didn't think about it, but now that you ask, goto-line is an interactive function that does much more than going to some line. And it will eventuall call forward-line, so I think it's a good idea to call it directly. Otherwise, you're correct about widen, but there must be a good reason why the user narrowed, I'd guess. The point is that, obviously, my command lacks a good documentation string. Sorry about that. -- __Pascal Bourguignon__ http://www.informatimago.com/ This is a signature virus.
