Yeah I type "blindly".
I think it's not really something to think about, you pick it up automatically after a while.
Typing speed has some effect on coding speed, but not that much. Typing twice as fast wouldn't make you twice as productive, not anywhere near that. But it does help some.
Additionally, hotkeys are also useful to learn. You can't really develop muscle-memory for navigating the GUI with a mouse, but you can and will for hotkeys.
