BTW, IMO typing the C with the middle finger, the X with the ring finger and the Z with the pinky seems ridiculous to me, even though that's what pretty much any typing tutor I've seen recommends. (As for the right hand, the brain-dead ISO mechanical layout makes it ridiculously easy to accidentally end lines with the key immediately left of the Enter key, e.g. ù on the Italian layout -- and there are several Facebook pages about that.)
