How can a global listener be implemented?

Question

How can you implement a global listener that will track keystrokes even when the app window is minimized in the background?

Answer 1

"I don't think that is possible. Once the frame is minimized, the application is no longer focused, and key event will transfer to the focused application or to the system."
