Except for the special signs that are at shift+number, I pretty much type without checking, and using all ten fingers as taught in the first two weeks of my "IT" course at age of thirteen or something. Often, when someone talks to me while I was typing something, I can focus on the person while finishing the sentence without concentrating or looking at the screen. However, I often have to edit my postings, but mostly English is the reason, not typos. That typing becomes automatical while my handwriting had really become unintellegible, even by me, got me thinking. Nowadays, I often take notes by hand, and write letters with my fountain pen (?), so by now it's become a bit easier to decode what I scribble on paper
