It does seem to require some mental "switch" or trick. If I look at the keyboard (assuming it's got QWERTY on the keycaps, which all of my keyboards have had), it "reminds" me to type QWERTY and I can do it. It's not really full-speed or facile but it's good enough and it's not hunt-and-peck, anyway. If I look away, I cannot type QWERTY.
