Did anyone know Ctrl+Alt+Shift hides every open VFP window and shows the VFP _screen window content?

20+ years using VFP and I never knew that. Boy would that have been handy to know.

CTRL+ALT+SHIFT
Hides all child windows while the keys are pressed down.
Hiding windows makes it easy to see output displayed in the main application window.
