This guy uses picks. One flat one to strum, and three whatever you call the fingertip ones to pluck, rather like a harp (a pinching motion). The way that works, he says, is you only have to be close, like within about three strings, since any note that plays WILL be in the proper key by virtue of the auto part. I'll stick with strumming for now. And he does say tuning is a big hairy expletive.
