At first, around 1996, it was common practice to make the Windows key act as Meta. However, because of the existing alternative keys for Meta in Emacs, the reintroduction of a hardware Meta key binding did not prove exceptionally useful. This made Super the next most frequently emulated key of choice, and thus it became the standard assignment for the Windows key under X11.

Most Linux software and documentation calls these keys “Super” keys. However, they are still referred to as KEY_LEFTMETA and KEY_RIGHTMETA in the kernel,[5] and some documentation such as that of KDE Plasma refers to it as just the Meta key.[6][7] “Windows” and ⌘[8] are also used in documentation.
