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*.
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.
