little magical rendering window shortcut ?

what is the shortcut for the resizable/moveable window that automatically renders whatever it is hovered over ??

It renders everything right away as soon as you move it on top of whatever object… Very useful for looking at objects from different angles without having to move cameras in place.

I don’t even know what it is officially called… I discovered it on accident but I have forgotten the shortcut for it.

Try Shift P

It is magic

yes that’s it! thank you !
