I had an experience like this when I switched to a Keyboardio split keyboard. It was impossible to use at first. Then I do some deliberate practice with a typing tutor app and now I love it so much I own multiple.

Is there a good tutorial for some of these advanced text editing features?

In particular I’d like to get platform independent shortcuts / key bindings. I use both windows and MacOS daily, and it throws off my muscle memory for shortcuts like “go to beginning of line”
