"I wonder what is the magic word?"

IMO, they have done the same for 737 that they did for 774.

The word "said" was removed from 774. ......"said switch" where the word "said" is an object of the invention.....changes to "switch" elevating that dedicated distinction.

747 got it's correction in June 2007....and relates to the micro-controller, multi directional switch with control circuitry.....as it interfaces to the ROM code(MOS).
