  1. 10:02 And one nice thing about scan codes is they don’t distinguish between modifier and non-modifier keys; it’s just “key «n» has been pressed” and “key «n» has been released”, it’s up to the software to decide if key «n» is a modifier key or not. And you can distinguish between e.g. left-shift and right-shift (they have different scan codes), and implement other fun custom behaviours.

  2. Newton’s Third Law, action = reaction; contemplate the Zen of physics: when you a press a key, the key presses back.

  3. 2:06 Or there would be, if your hardware implemented “n-key rollover”, which means it can distinguish every possible combination of keys being pressed at once. Not sure if current keyboard hardware actually supports that.

  4. 3:34 What about “buckling spring”, e.g. Cherry MX switches?

  5. I don’t know why that “keyboard not found, press a key to continue” thing is considered such a joke. It makes sense, after all, that if the hardware requires a keyboard to continue, it should wait for you to connect one.
