If I could add one thing to the list I would include `cib` as equivilent to `ci(` for changing everything in a set of parentheses (or brackets for the mnemonic's sake). For me at least the `b` is easier to reach than the `(`.

I need to use `z` for refocusing more

I notice it mentions Ctrl-a and Ctrl-x which "increment or decrement any number after the cursor on the same line". I hate these shortcuts because several times I've accidentally pressed them (e.g. on some level thinking I'm in Spacemacs or in readline) and introduced a hard-to-find bug into my code without knowing it.

Agreed. I love vi, but this is almost always an anti-feature.

To disable, add these lines to .vimrc:

  map <C-a> <Nop>
  map <C-x> <Nop>

Won’t you spot that through you source control?

Shows how crucial customizability is because I don't think I can work without being being able to rely on <c-a/x>, and more importantly g<c-a/x>.

They can be quite useful, but I just stopped using them due to muscle memory of Ctrl-a for screen / tmux.

Having suffered through learning highly configurable software tools independently enough times, I agree completely with "digesting one or few commands" at a time works better for me too.

Spitballing:

We could probably make a general solution for organically producing "learning guide" if power users 1) share their custom configurations and share the frequencies of commands they use.

Start with the general configuration, knowing nothing about the commands the tool offers. The learning guide is just a queue of "here's the most common config edit that you don't have" and "here's the most common command that you don't know about."

We are already share configs with eachother via the dotfiles pattern. We somewhat share command patterns via coding streams. Seems doable.

(In general, making it easier to learn new tech and for devs to share / refresh the learning material for a new tech seem underdeveloped.)

I agree. That said, I also like to have a more complete guide and pick and choose what could be useful for me.
