I don't remember many of the words, but my hands can wander round the cockpit arranging the switches in the familiar pleasing-and-eye-catching manner. It's like they aren't a part of me - well weird.
In a similar vein I once found myself (on the ground) having changed the drive configuration on a helicopter, a procedure that involved moving throttles and switches with much dexterity and panache, with no conscious recollection of having done it! Obviously this was before the days of CRM where we trained the guy in the other seat to shout "Don't touch that you knob! We're still in the air".
