what is the command button on windows keyboard
Command key - wikipedia Command key Jump to : navigation , search For the same keyboard key in Windows , see Windows key . The Command key ( ⌘ ) , also historically known as the Apple key , clover key , open - Apple key , splat key , pretzel key , or propeller key , is a modifier key present on Apple keyboards . The Command key 's purpose is to allow the user to enter keyboard commands in applications and in the system . An `` extended '' Macintosh keyboard -- the most common type -- has two command keys , one on each side of the space bar ; some compact keyboards have one only on the left . The `` ⌘ '' symbol ( the `` looped square '' ) was chosen by Susan Kare after Steve Jobs decided that the use of the Apple logo in the menu system ( where the keyboard shortcuts are displayed ) would be an over-use of the logo . Apple 's adaptation of the symbol -- encoded in Unicode ( and HTML ) at U + 2318 ⌘ ( HTML & # 8984 ; ) -- was derived in part from its use in Scandinavian countries to denote places of interest . The symbol is known by various other names , including `` Saint John 's Arms '' and `` Bowen knot '' .

The first model on which it appeared was the 1980 Apple III , where there are two monochrome Apple keys , both to the left of the space bar on the lowest row of the keyboard . Two other early Apple computers , the 1982 Apple IIe and the 1984 Apple IIc , also had two such keys , one to the left and one to the right of the space bar ; in these models , they mapped to the first two fire buttons of an attached joystick . This allowed for flexible combinations of a modifier key and base key ( such as Open - Apple with C for Copy ) with just a few extra wires and no ROM changes , since the Apple II could only register one key press at a time ( Shift and Control keys were handled in the keyboard encoding hardware which generated ASCII codes ) . In all these cases , the left Apple key had an outlined `` open '' Apple logo , and the one on the right had an opaque , `` closed '' or `` solid '' Apple logo key . The Apple Lisa had only the closed Apple logo . When the Macintosh was introduced in 1984 , the keyboard had a single command key with a Looped square symbol ( ⌘ , U + 2318 ) , because Steve Jobs said that showing the Apple logo throughout the menus as a keyboard shortcut was `` taking ( it ) in vain '' . Thus , the ⌘ symbol appears in the Macintosh menus as the primary modifier key symbol . The original Macintosh also had an Option key which was used primarily for entering extended characters . In 1986 , the Apple IIGS was introduced . Like the newer Macintosh computers to come , such as the Macintosh SE , it used the Apple Desktop Bus for its keyboard and mouse . However , it was still an Apple II . Apple changed the keys on the IIGS 's keyboard to Command and Option , as on Mac keyboards , but added an open - Apple to the Command key , for consistency with applications for previous Apple II generations . ( The Option key did not have a closed - Apple , probably because Apple II applications used the closed - Apple key much more rarely than the open - Apple key ; thus there was less need to keep it around . ) Because any ADB keyboard could be used with the IIGS , all of Apple 's ADB keyboards -- even those intended for the Mac -- also required the open - Apple , and it stuck for more than twenty years , causing confusion long after the Apple II series went out of production . The Apple symbol was removed in the keyboard 's 2007 redesign , making room for the key 's name to appear . The word `` command '' is now printed on the key . Next ( edit ) NeXT keyboard command key On the keyboard of the NeXT Computer that key was marked Command in green . The menus were not marked with a symbol denoting the command key . Besides being used as a modifier key for keyboard shortcuts it was also used to alter the function of some keys . Command + ⇧ Shift toggles alpha lock , Command + Return sends Enter and Command + 🔉 Volume - down toggles Mute . The functions were printed in green on the front side of the modified keys . This was also done on the Z , X , C and V keys ( Undo , Cut , Copy and Paste ) ( Left ) Command - Alternate - * triggers a non catchable hardware reset thereby hard rebooting the computer . ( Contrary to Ctrl + Alt + Del on a PC compatible computer which triggers only a software reset ) On the NeXT ADB keyboard , the Command keys were replaced by keys labeled Help and the Command key morphed into a wide Command bar in front of the space bar Function ( edit ) The purpose of the Command key is to allow the user to enter keyboard commands in applications and in the system . The Macintosh Human Interface Guidelines have always recommended that developers use the Command key ( and not the Control or Option keys ) for this purpose . A small set of keyboard commands ( such as cut and paste , open and save ) are standard across nearly all applications , and many 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 ( edit ) See also : Looped square and Bowen knot Swedish road sign no . H22 A Bowen knot 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 Fornminne -- ancient monument -- by Swedish Mac users and Seværdighedstegn 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 it has since been told to her that the symbol had been 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 . The symbol was included in the original Macintosh font Chicago , and could be inserted by typing a control q key combination . In Unicode and HTML it is encoded , respectively , as U + 2318 ⌘ Place of interest sign ( HTML & # 8984 ; ) . On other keyboards ( edit ) On USB keyboards , the Command keys are mapped to standard keycodes reserved for GUI functions . On a keyboard made with the Microsoft Windows logo , the Windows keys are identical in function to the Mac Command keys , as is the ( ( Meta key Meta ) ) key on a Sun or another Unix - oriented keyboard . Conversely , when an Apple USB keyboard is used with other operating systems , the Command keys function as Windows keys or Meta keys . On a Windows keyboard the position of the ⊞ Win and Alt keys are swapped compared to the position of Alt and ⌘ Command keys on an Apple keyboard . In macOS this can be configured in the keyboard preferences ( Modifier Keys ... ) so that the Windows Alt key ( next to the space bar ) becomes the Mac ⌘ Command key and vice versa so that users do not have to change their Motor learning . All the modifier keys , along with the ⇪ Caps Lock , can be remapped to whichever modifier key function the user wishes , so users of traditional Unix style keyboards may choose to use the ⇪ Caps Lock key as a ⌘ Command key or other modifier . Windows does not provide such a configuration option . References ( edit ) ^ Jump up to : `` Clover key - Definition '' . Mondofacto .
