Typing while looking at the keyboard just feels so clunky to me. Touch typing is much faster. Thanks to muscle memory, my fingers move faster than my eyes could follow.
I hybrid type. I probably look for about 50% of the typing I do. I have no training I have just been using a keyboard so long that I really just kind of point my eyeballs at it and touch type. I often realize I am typing while looking at the screen and suddenly start making mistakes where I was not before. I cannot consciously touch type. My eyes do not identify each key press but definitely keep spatial orientation though I am definitely not looking at each letter pressed. Oh, yeah, I type about 110 wpm with occasional errors and around 80 wpm with zero errors. I can use a number pad entirely without looking, though.
I just did a random typing test from the
first hit on Google. I got 95 wpm with 1 error, 94 wpm adjusted. Second attempt, 104 wpm with 1 error. Third try, 101 wpm with no errors. I did make an effort to keep my eye out for errors and to backspace and correct them, which significantly impacts the overall wpm. I would do better typing my own thoughts (so I don't need to move my eyes between the reference and my actual output).
I know some people can type really fast via hybrid touch typing and "hunt and peck", but it blows my mind.
I learned touch typing in Jr. High. Had a lot of trouble at first, but now it's second nature. Number pad was easier, but I'm not sure how well I can use it now. I usually don't need to use the numpad so I am out of practice (and there isn't really a numpad on my laptop).
Edit: Oh, and there was no particular training. The teacher just said, "try this" and had us practice, mostly by having us type things while our hands were covered by a sheet of paper.
