If you can type at any speed while pecking at keys you must have muscles made of pure lightning.
That said, what he does certainly looks like either an imitation of touch typing while pressing random buttons, or a method of touch typing that I’m not aware of. It certainly looks too fast for him to be checking every letter he types.
It's not hard to learn to touch type from having some reference even without al\ fngers or both hands available.
My error rate is pretty high due to recently switching keyboard software, but I can manage about 40-50 wpm on a phone keyboard and my main reference points are the corners.
Interested in what you mean by your first sentence. What's a high speed in your mind? I can type prose at about 90 WPM on a Macbook with basically just my index fingers, without looking.
What I see as pecking is having two index fingers tap down on the keyboard after locating the required letter.
I’d be amazed if you can do 90 wpm with just your index fingers regardless of strategy though. With two fingers and an average of 4 letters per word you need to tap 90 / 60 = 1.5 * 4 = 6 / 2 = 3 letters per second per finger (more if your words are longer).
I trust you can do it, but I can’t imagine what that looks like.
