What comes naturally when using a computer daily is usually bad touch typing, i.e. not having to look at your fingers, but typing with only four or maybe six of them using weird, possibly unhealthy, techniques.
I can't stand those supposedly ergonomic keyboards that have been chopped in half, and I didn't understand why anyone would want one until I recalled people learned touch typing.
My naturally acquired typing style involves me holding my hands hands in just about the same angle as those "ergonomic" keyboards, but just using a regular keyboard. Fingers rest on LShift, A, W, D, and K, O, P, Ø with both thumbs on Space.
Should be noted that's on a "105-key" Nordic keyboard with US layout when not writing Norwegian, so the Ø becomes '.
For me this has worked quite fine for over 20 years. I haven't bothered measuring my typing speed because it's never the limiting factor.
i developed a pretty fast way of typing naturally, using 7 or 8 fingers.
unfortunately it caused wrist strain.
i could not use split ergonomic keyboards because some keys where "mapped" to the wrong hand for that.
i also could not simply learn "proper" touch typing on a qwert layout because my typing habit was too strong.
in the end i learned touch typing on dvorak to fix my wrist issue. maybe after 10 years i'll have unlearned qwert typing enough to go back? (not sure i would, i do prefer dvorak, it just feels silly to type at snail speed on others ppls keyboards).
