Even the Linux nerds who customize everything about their computer are probably still using the QWERTY keyboard layout. I’ve seen a lot or “arch btw” but never seen “dvorak btw”.
I use Dvorak btw.
How do I make Dvorak make sense in my brain?
Typing is one of those things that is just experience. Grab a typing test program and put in the time. It took me a few weeks, starting with doing simple things like the equivalent of jkjlj; sets until my pea brain got the minimal amount of muscle memory to be able to use it in the wild. YMMV but I can still use QWERT as well, but it feels weird and not as natural anymore.
