I've noticed that by being a good typist the keyboard is almost like an extension of my mind. I simply don't notice it at all. When combined with a powerful editor like vim, it's almost magical how well integrated I feel with the code that I am writing.

I also experience what it's like to not be in this state whenever I switch to a keyboard with a slightly different layout than I am used to. My movements feel clunkier and I spend time context switching between being 'in the code' and being focused on where my fingers are on the keyboard.

For anyone who hasn't experienced this state due to poor typing skills, try to learn, it's worth it!
