Sorry for a very basic question, could you be so kind to give basic advices on learning how to touch type (it seems like you are)? Even if the theme of a series is too difficult for me, but it's extremely interesting to watch and i'm very impressed by the easiness of your typing of such complex statements.
Cover the keyboard so you don't look att it, or paint or put stickers on the keys or get blank keycaps. Or try hard to never look at it. I have a keyboard with all blank caps, but still have the keys memorized so that doesn't matter that much. keybr.com helped with accuracy, monkeytype.com (try "master" difficulty so any error stops immediately) or typeracer.com sometimes to test. typingclub.com is pretty good also, goes slow and has a ton of lessons to slowly drill in typing, but you have a "kiddy" aesthetic and have to skip upsell prompts. Go slow and get perfect accuracy, your speed will increase over time naturally from muscle memory, and from internalizing groups of keys at once in different words. Typing of The Dead is fun and puts you under pressure to go faster, steam has the sequel to it. Or other typing games. It's mainly practice, pinky keys are still kind of awkward for me, and 'b' and some other things still give me trouble. I only use my left thumb for space and never use the right shift key, but want to fix that. Still have to look more into ergonomic keyboards eventually. Many many hours of building muscle memory is all it comes down to though.
