FYI, I didn’t get an ortholinear keyboard for a long time because I was worried that I wouldn’t be able to type on a normal one – and that was true for the first few months. Now I can switch without a problem, even though the keys are mapped differently. Escape is at my right thumb with my ErgoDox, and it’s on the menu bar thingy on my macbook. Z and / double as my control keys on my ErgoDox and I use the normal control keys on my laptop.
But it’s just not a problem, strangely enough.
EDIT: Related: I can no longer use Vim for even the most basic things, since a week after I started using Kakoune. Why is this different? No idea.
