The command "screenkey --show-settings" is used to run the "screenkey" program with the argument "--show-settings".

"screenkey" is a utility that displays the keys being pressed on your screen, which can be helpful for presentations, tutorials, or screen recordings, allowing viewers to see the keyboard input.

By running "screenkey --show-settings", the program opens its settings window instead of directly displaying the keys on the screen. This allows you to customize various aspects of the keys' appearance, such as size, color, position, opacity, and animation. It provides a graphical interface where you can adjust these settings according to your preference.

By default, without the "--show-settings" argument, "screenkey" will directly start displaying the keys on your screen using the default settings.
