推荐答案

要了解这些值是什么，您需要查看这个 [ ^ ]表。那些值实际上并不对应于任何形式的按键（你会按什么键来获取NUL？）因此它们不会被表示为键码。

To understand what those values are, you need to take a look at THIS[^] table. Those values don't actually correspond to any form of keypress (what key would you press to get a NUL?) so they aren't represented as keycodes.
