How can I return a hidden window by the same program?

[Blank6]

Hey,
I would like my program to remain in the background until a combination of keys is pressed, say Ctrl+1.
So no problems in hidding the program (Through API or just .Hide()), but how can I make the program still input keys until the right combination is pressed?

Thanks ahead!

You will have to use an OS level hook to monitor the keyboard
