How to get all system events using SDL2?

Question

HTML

I want to receive all system messages (for windows desktop system), not for the current window. To understand, I need functionality like AIMP, for example, the use of global keys. To call my application. How can I do this with SDL2. If this is not possible, perhaps sfml can be used?

What you want is called hooks. Google SDL2 windows hooks.
