I love typos. They show how involved our minds are with what we are communicating. We forget to watch our fingers. sort of like patting our head and rubbing our tummy at the same time. Or, for me, trying to play a piano. I can't get my right hand and my left hand to do two completely different things. The Oboe I could play.
My typos, not sure what they would be classed as.
Probably a short circuit as typing is a completely different neural path from speech or writing.
