The action is one of `GLFW_PRESS`, `GLFW_REPEAT` or `GLFW_RELEASE`. The key

will be `GLFW_KEY_UNKNOWN` if GLFW lacks a key token for it, for example
_E-mail_ and _Play_ keys.
The scancode is unique for every key but is platform-specific, so a scancode
will map to different keys on different platforms.
The key will be `GLFW_KEY_UNKNOWN` for special keys like _E-mail_ or _Play_ that
don't have a key token. Those keys will still have unique, if platform-specific
scancodes.
The scancode is unique for every key, regardless of whether it has a key token.
Scancodes are platform-specific but consistent over time, so keys will have
different scancodes depending on the platform but they are safe to save to disk.
Key states for [named keys](@ref keys) are also saved in per-window state arrays
that can be polled with @ref glfwGetKey.
