How about keeping it as a convenience? I find it easier to type ? than help and often use it instead. It's sufficiently hidden to not cause any confusion for those who don't know and convenient for those who know. I agree with Peter that it should not be something that causes that much trouble that it would need to be removed immediately (or even in the future). Regrads, BALATON Zoltan
