Typing

If you type a word wrong, erase it, and re-type it, you will often reproduce the exact same reversal of letters of the first attempt.  I've sometimes done this three or four times with the same word.  You have not identified the reason for the mistake, and you are actually reinforcing it in muscle memory rather than correcting it. I live on a street called Emory, and I often type is at Emorgy, for no good reason.  My fingers just want it to be energy, perhaps.
