I'm sorry sir for this question. I hope you have warm heart to answer me. I'm a video editor.
But I want make application that can read what key press even this application is not focused/active (show behind other window)

Can you give me advice or recommendation. How to code that application still can run and can read/get keypressed even it is not focused/active.

I've make a application to show what button press, but when it goes to other apps. It can't read/know what key I have press. Sorry for my english, thanks. I'm very respectfull if you want answer my question.
