How is that meant to reduce confusion? What do you press to enter an 'a' ? A. The keyboard keys though labelled with capital letters are by default lowercase letters. That's because they are conceptually and nominally the same character. If you want to avoid the confusion of having multiple buttons with the same label, it's not enough to simply make them visually different. (the same goes for adding underlines) Did you ever take a test at school to determine your learning style, Visual, Auditory or Tactile? Different people assimilate information in different ways. To me, A, a and A are all processed the same way, because what I hear in my head when reading all three is the same. That isn't to say that I can't tell the difference, I can, but there is certainly room for confusion, especially if there's a delay between learning something and using it, or in spoken communications. - Neelix
