Char to KeyCode As3

Char to keycode looks pretty impossible... But I think I found a script that does it...

Why Char to keycode?

Well, for readability.

Example: keyBoardListener.BindKeyToFunction("K",true,theFunction);
K = the K key.
true = case sensitive. AKA, bind to capital K, not the k key.
theFunction = the function that will execute when you press the k key.
