Tom beat me to it. The Caps Lock button engages Auto Advance. Very handy for sorting through imported images. Turn Caps Lock on, select the first image, press E for single image view, then press P for pick or U for unpick. It automatically goes to the next image. When you're done use the 'Refine Photos' command to set Picks to unpicked and Unpicked to rejects. Standard part of my workflow.
P.S. The only stupid question is the unasked one.
