In my case, the first visual editor that worked under Unix was DED from the Australian Distro. it only worked on a VT100, but that's was what i had :-), then came emacs, so im one of the few that doesn't know vi. danny _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
