other commands are standardized (Find, Show Fonts). If an application needs more shortcuts than can be obtained with the twenty-six letters of the Latin alphabet, double modifiers such as Command+Option are used. One advantage of this scheme, as contrasted with the Microsoft Windows mixed use of the Control and Alt keys, is that the Control key is available for its original purpose: entering control characters in terminal applications. (Indeed, the very first Macintosh lacked a Control key; it was soon added to allow compatible terminal software.) The Macintosh keyboard's other unusual modifier key, the Option key, serves as a modifier both for entering keyboard shortcuts and for typing text—it is used to enter foreign characters, typographical symbols, and other special characters. Origin of the symbol The ⌘ symbol came into the Macintosh project at a late stage. The development team originally went for their old Apple key, but Steve Jobs found it frustrating when "apples" filled up the Mac's menus next to the key commands, because he felt that this was an over-use of the company logo. He then opted for a different key symbol. With only a few days left before deadline, the team's bitmap artist Susan Kare started researching for the Apple logo's successor. She was browsing through a symbol dictionary when she came across the cloverleaf-like symbol, commonly used in Nordic countries as an indicator of cultural locations and places of interest (it is the official road sign for tourist attraction in Denmark, Finland, Iceland, Norway, and Sweden, and the computer key has often been called —ancient monument—by Swedish Mac users and —landmark signs—by Danish users). When she showed it to the rest of the team, everyone liked it, and so it became the symbol of the 1984 Macintosh command key. Susan Kare states that she has since been told that the symbol was picked for its Scandinavian usage due to its resembling the shape of a square castle with round corner towers as seen from above looking down, notably Borgholm Castle. However, the symbol is used in many places in Scandinavian history, for example on a 5th century picture stone from Gotland, and first usage of the shape as a sign for a place of interest was suggested by the Finnish Local Heritage Federation in the 1950s. The symbol was included in the original Macintosh font Chicago, and could be inserted by typing a key combination.
