Aphantastic here. I never learned to visualize a keyboard and went with blank keycaps to force myself to learn with weeks of painful brute force muscle memory. I learned Colemak which is much less finger travel and helped too as many words can be typed with home row.

I also do everything I possibly can on the command line because it is -one- interface to learn with a universal history to reference past commands vs randomly mucking about in GUI interfaces I can not picture in my head that are wildly different in every application.
