How to get the current screen

    Calling tv:mouse-default-superior is a good answer.  Note that it takes a window as
    an optional argument, defaulting to the value of *TERMINAL-IO*.
    Using tv:mouse-default-superior
    gives more robustness in the face of various unusual situations, for example if you have
    a color screen and a monochrome screen sharing the same mouse, it will use the screen
    the mouse is on even if the window you give is on the other screen; for menus you
    generally would rather have them appear next to the mouse.

A curiosity flag raises which asks, "How does the program know which mouse to
base this function on?"  Remember, when running X windows, there's a separate
mouse for each console.  I'm just curious; so, please don't spend a long time
producing a rigorous response.
