> Pardon my curiosity, did you type this on a keyboard by touch typing? If so how do you recognize and correct typos?
I'm merely a sighted user here, but I can personally attest that when you've mastered touch-typing, you can tell when you make a mistake and correct it without needing to look at the screen. It is a bit of an eerie feeling the first time you do it.
Full disclosure: I touch-typed this reply, and I made five mistakes when doing so, and fixed all of them without looking at the screen.
I've touch-typed for 20 years and sometimes a random friend (whose job isn't related to computers) catches me doing it and is either amazed or thinks I'm showing off. To me, I'm just typing. Like other commenters, I also self-correct while doing it.
I never learned touch typing, so I was unaware of that. I pick type with both hands without looking at the keyboard, but I have to look at what I'm typing on the screen to know when I've made a typo.
