I’ve recently been looking into some tools that provide quick or painless help like pop up snippets with descriptions and cheat sheets, got any recommendations?

Navi is good for generating personal cheatsheets:

But for Git, I can't recommend lazygit enough. It's an incredible piece of software:

Cheaters: https://brettterpstra.com/projects/cheaters

I've found tldr to be useful
