I have no trouble hitting any key on the keyboard without looking at it. I can lock eyes with you while you dictate and type the email you would dictate, perfectly (albeit not at the a normal dictation speed, I only type about 100WPM at most). I can fix errors as I type using backspace because I always know where I am and where I made a mistake.
The important part is learning this correctly.
I had fortune of going to school where for a single semester I had a course in typing documents on an electric typewriter, with a professional typewriting teacher.
Because it was so long ago I have trouble understanding not being able to type. I lay my hands on the keyboard and they just do it without me even thinking about it. I don't even know where keys are. If you ask me where a particular key is I can only point to handful of them. Otherwise I need to put my all fingers on the keyboard and think the key and then observe which finger goes where, and only then I know where the key is.
