说明
showkey prints to standard output either the scan codes, the keycode, or the ASCII code of each key pressed. This is useful for debugging keyboard-related issues, key remapping, and understanding keyboard input at a low level. In scancode and keycode modes, the program runs until 10 seconds have elapsed since the last key press or release event. In ASCII mode, the program terminates when the user types Ctrl+D.
