Hey guys/girls, Im a new user to a mac, about a month now and have a question if you dont mind me asking At home im using a mac and when I move my mouse into the 4 corners of the screen, they all have some sort of functionality and affect my windows. Bottom right: clears screen top right: shows all windows open top left: shows all open of the current type etc I was trying to explain it to a friend but had no idea what to call it. Is this a feature to turn on? does it have a name? thanks!
