I keep meaning to get back into Helix, I'm super close to setting up an "vi=hx" alias. I had Claude make me a cheat sheet, but I haven't gone over it, here it is if it helps anyone: https://box.linsomniac.com/HelixCheatSheet.pdf
Heh, "vi=hx" was exactly how I forced myself to spend a week in helix. Just go for it
Your cheatsheet has some hallucinations in there. For example there is no :git command
you can do "! git status" etc
There is some other integration for git like SPACE + g to see file changes for example
