It's not two buttons. Assuming the remote is on TNR, which it will be unless you've been controlling something else with it, hitting the selected input, e.g. AM-FM, turns the 990 on with FM selected. That's one button as I count them. If you have been controlling something else, e.g. playing a DVD using the 990 remote, and you want to, say, play a record (as some of us do from time to time), then TNR + PHONO is two buttons, yes - but the more "traditional" way would be TNR + POWER + PHONO: three buttons.
