Wait, I need you to please elaborate on this. Where was he sourcing all code he pasted? Did he have a "snippet file" like a painter with a palette or something?
Sometimes he would need a portion of a word and he would remember that it was in an email he had open, and he would alt+tab and grab the portion of the word from the email, then alt+tab back to the editor and paste the word portion in.
He would go to extreme lengths to not have to move his hands to the home row on the keyboard.
