Yes, horizontally or vertically. Start vim, type `^Ws^Wv' where ^ is
Ctrl, and you'll have three windows.

undo a few times, then make a new edit, and you old undone edits are
still available, but on another branch; the original one. Occasionally

What actually happened was that I was in the process of adding
multiwindows to vi when we installed our VAX, which would have been
in December of '78. We didn't have any backups and the tape drive
broke. I continued to work even without being able to do backups.
And then the source code got scrunched and I didn't have a complete
listing. I had almost rewritten all of the display code for
windows, and that was when I gave up. After that, I went back to
the previous version and just documented the code, finished the
manual and closed it off. If that scrunch had not happened, vi
would have multiple windows, and I might have put in some
programmability—but I don't know
