Nice checklist...

I'm not quite convinced about this as general advice :

> If you’re like me and never learned to touch type properly, just use the arrow keys, it’s fine, don’t worry about it.

When I decided to go all-in on Vim keys some time ago (trying to find plugins for everything), it didn't take long to transition to hjkl. I think it's easier and more convenient to stay near the home row rather than moving my hand over for the arrows. I don't strictly touch type either.
