<p>This function sets the key callback of the specified window, which is called when a key is pressed, repeated or released.</p>
<p>The key functions deal with physical keys, with layout independent <a class="el" href="group__keys.html">key tokens</a> named after their values in the standard US keyboard layout.

<p>When a window loses input focus, it will generate synthetic key release events for all pressed keys. You can tell these events from user-generated events by the fact that the synthetic ones are generated after the focus loss event has been processed, i.e. after the <a class="el" href="group__window.html#gac2d83c4a10f071baf841f6730528e66c">window focus callback</a> has been called.</p>
<p>The scancode of a key is specific to that platform or sometimes even to that machine. Scancodes are intended to allow users to bind keys that don't have a GLFW key token. Such keys have <code>key</code> set to <code>GLFW_KEY_UNKNOWN</code>, their state is not saved and so it cannot be queried with <a class="el" href="group__input.html#gadd341da06bc8d418b4dc3a3518af9ad2">glfwGetKey</a>.</p>
<p>Sometimes GLFW needs to generate synthetic key events, in which case the scancode may be zero.</p>
