+Frequently asked questions
+==========================
+
+ Q. When I press a movement key, it sends two keypresses?
+ A. Turn off numlock. You are using a keypad on a full keyboard.  SDL2 does not support differentiating between number keypad presses, and number key presses. This means we cannot either.
