Select - Set
Mary, surely you are being just a little pedantic? Selectors can be used to SET speeds, headings etc etc. e.g. AutoThrottle Speed Selector used to set the desired speed, Heading Selector used to set the desired heading, Altitude Select control used to set desired altitude in a Cabin Pressure controller etc etc. Who really cares whether we "set" or "select" such as above so long as the correct numbers appear?
