Based on what you were saying earlier, I kinda figured you missed tagging a page or a button.
Regarding your comment about errors. You had said that you wanted to do a keyboard early on in this thread and so I gave you the script code that should go in the shift button such that when you press the 'A' (KeyA) key on the keyboard that it would execute one of 2 actions. The code in the Shift button should be used only to change the state of the variable (shift vs unshift vs ctrl, etc) and then of course change the labels on all your other Key(x) buttons. The exercise of writing that code is left for exploration.
