Looped square

Symbol

The looped square (⌘), also known as Saint John's Arms, Saint Hannes cross, and as the command-key symbol due to its use on the command key on Apple computer keyboards, is a symbol consisting of a square with outward pointing loops at its corners. It is referred to as a looped square, for example, in works regarding the Mississippian culture. It is also known as the place of interest sign when used on information signs, a practice that started in Finland in the 1950s, spreading to the other Nordic countries in the 1960s.
