Okay, states are fixed. The one thing I realized I had done before regarding the states was that I kept asking myself, "well, what if a person doesn't select the next level to learn what it is?" Then that won't hide the previous state. For instance, if I press Enter on character level 1 and then choose not to press enter on character level 2, but choose to press enter on character level 3, then the character level 1 state is also still selected. But... for now, that's the way it is set up. If there is another way/trigger/variable to negate this issue, please let me know.
Also, and yet another question I had asked myself when I initially created this slide...Will sighted learners be using their tab key to navigate, or will learners who are blind be the ones using tab to navigate?
