2. print the key value on the terminal
3. loop (rinse and repeat)

Select one of the keys or be the "exit" key. Exit the program if this key is pressed. (Start with 'q' as the exit key.)

Note: The window must have the focus to receive key strokes. Try putting the focus on another window and see what happens.
