Что такое клавиша Super?
When you press the Super key, the Desktop is displayed. This key can usually be found on the bottom-left of your keyboard, next to the Alt key, and usually has a Windows logo on it. It is sometimes called the Windows key or system key.
На клавиатурах Apple вместо клавиши Windows расположена клавиша командная клавиша ⌘, а на Chromebook — клавиша со значком лупы.
