Perhaps you could use an array of function pointers or simply split each conditions into a single callback to reduce the lambda length?

or maybe remove the two white spaces, but I'll try that :)

Related to: - #195 Used in [RollingBall/use-new-input-plugin](https://github.com/EngineSquared/Rolling-Ball/tree/use-new-input-plugin) Notes: - Explaination about the glfw window user pointer [here](https://discourse.glfw.org/t/what-is-a-possible-use-of-glfwgetwindowuserpointer/1294), this can be useful later - The glfw joystick callback `glfwSetJoystickCallback` (which indicates when a controller (dis)connects) is not supported because of glfw's handling of user data pointers for joysticks (it is handled per joystick and not per window), but joystick operation can be handled through polling. - The `UpdateKey` system has been removed. Why would pressing "escape" always close the window ? --------- Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com>
