On Unix and Unix-like operating systems, the key is usually given the X keysym "Super" (on earlier versions "Meta" was often used), and turns on the shift bit called MOD4. Most desktop environments use it much like Windows, with press+release popping up a primary menu similar to the Windows start menu (GNOME Shell bringing up the Activities Overview, KDE Plasma, Cinnamon and most other desktop environments pop up their main system menus), and with combinations with letters performing actions such as run-command, often with the shortcuts and actions copied from Windows. A common action that is not shared with Windows is for the key to allow dragging a window around from any location without raising it, and in the Compiz window manager it causes the scroll wheel to zoom in or out of any part of the desktop.
