Seems like there’s a bunch of Sapiens books. Which book and which chapters were you thinking of?

Thanks for passing this along. I’ve been wondering what the next steps would be.

I don’t mind neovim comments here. But you should know there’s a large neovim community as well.

It’s not too hard to create your own vim help. I named mine myhelp. So I can type :myhelp and see all the commands I can never seem to memorize.

I have never used Vim in the manner you show in the Vim example. I use ex commands seldom — usually when I need to make mass changes to a file. You are really doing things the hard way if you use an ex command to add a semicolon at the end of a line.
