<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. If you want to input text, use the <a class="el" href="group__input.html#ga556239421c6a5a243c66fca28da9f742">character callback</a> instead.</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>
