Still, you can use the three finger method for major and minor chords, which is what I normally do. The old one-finger-equals-major mode is still available. I would think the only people that would have trouble would be those that routinely use one-finger major chords. I am assuming on the PSR-2000 you have to consciously activate the key signature, so it is only there when you think it would be helpful. Anyway, if Yamaha has implemented this feature, I appreciate it. Also, thanks to Uncle Dave for letting me know where I could find the feature I was looking for implemented.
