Sometimes I step away from the screen and talk out is happening in my head.
Often times my coworkers and I will ask each other for help. Much of the time the person explaining will see the problem as they explain it to the other person. Usually before the other person has a chance to get the full explanation.
Awesome! I found out this worked for me years ago when I was a lone dev. I would walk around muttering to myself. Glad to know there is a term I can use now!
