Sounds like it may be a little too complex for me to just teach myself. I asked, though, because that's how I have learned how to do countless things over the years -- just learning enough to get started, following how-tos, instructions, guides, advice from others, et cetera.

Thanks again for the advice, guys. Fortunately, this is not a critical situation for me. It's just something I think about every now and then when I see these unused buttons on the phone.
