I've come across "action sequences" in psychology writing, which seems to be the active form of procedural memory. Over time well rehearsed actions can move from conscious parts of the brain to parts focused on motor actions like the basal ganglia ( and its friends ).

Probably easier to focus if distraction has moved to the old lizard brain.

I can't find an obviously good source to share, but there's plenty of research to check out.
