WB is white balance.
I wish I felt that way and do understand your frustration Ellen. Coming from the very simple (a few modes only) P & S world I am having major button & menu overload.
The good part is, that you can still take outstanding pictures with your camera on auto, or better yet, "Program", while you are learning about all those settings. And remember, depending on the type of work you plan on doing, there's many of these features you will probably never need. Many of them are just plain ole novelity. At least to me, and many others.
