I remember that i did not used to make typos but since a particular period that i vaguely rememebr i have noticed that i make more and more of them. It was some kind of switch, not a long period that the transition took place in. I could not pinpoint the reason behind it but my theory is that my speed of typing increased and with it the amount of incidence of hitting the wrong keys. I think it started primarily when my right digits hit faster than my left ones, so letters get switched. It might be neurological or i picked up some trait from some exercises related to reflexes(martial arts), hard to say but all i could recommend is typing slower or trying to write with the style of never taking your hands off the keyboard and typing with all 10 fingers instead of just few, like most of us do. Hard to switch to this style without actual desire to do so, but it is a solution.

I have also switched to mechanical keyboard because i have noticed that i was missing letters despite feeling that i hit the keys. So having more sensitive keyboard helped to mitigate quite a bit of typos. I have the brown tactile switches but i think i would go for the more sensitive red ones in the future to decrease the key travel distance for key press detection.

BTW dyslexia is more about reading rather than writing and it concerns only languages that are not phonetic.
