Currently I'm a #vim user with only two plugins loaded by vims own system no packer or anything. They are the gruvbox theme and colorizer to color HTML color codes.
I've been researching to see if I could work with #nvi and wondered about undo history and found that it might be possible ?

u

Undo the last change made to the file. If repeated the u command alternates between these two states. The . command when used immediately after u causes the change log to be rolled forward or backward depending on the action of the u command.
If you're an nvi user what other tips or hacks are there that I should know about ? I don't suppose there is some magical way to theme it ?
