I switched out keycaps IRL, not in VR. The idea was that, not being able to cheat by looking down would help improve my typing faster by forcing me to memorize the keys better. I’ve only gone from mid-50s wpm to now about 60ish but it’s helped more with the uncommon keys that don’t move the average as much. It’s those uncommon keys that kill me in VR though so it feels like a bigger bump.
