I was finished taking shots of Xmas displays and was getting into my car while trying to turn off the D200. Apparently I was pushing the selector switch the wrong way to turn it off and it "felt funny" so I looked down and saw that the top display was lighted! Later, looking closer at the on-off switch I saw the icon..... I had gone through the manual selectively, trying to just learn the menus, exposure, metering and focusing settings, but never saw the item about the lighted display. My D70 didn't have this, so I wasn't expecting it. Nice feature.
