How do I get it to hook the keys pressed and display them in the list box on the form inside and outside of the program?

 

I wish to create a macro recorder program, to play them back I already have achieve this by doing: SendKeys.Send();  so am looking for the opposite, I changed Keypreview on the form to True but still unsure where to go from there?
