Where can I find a list of Mac virtual key codes

Question

I m using CGEventCreateKeyboardEvent and need to know what CGKeyCode values to use   Specifically  I am after the key code for the Command key  The docs give examples for other keys  z is 6  shift is 56   There must be a list of Mac virtual keycodes somewhere

Here are the all keycodes      Here is a table with some keycodes for the three platforms  It is based on a US Extended keyboard layout    http   web archive org web 20100501161453 http   www classicteck com rbarticles mackeyboard php  Or  there is an app in the Mac App Store named  Key Codes   Download it to see the keycodes of the keys you press   Key Codes  https   itunes apple com tr app key-codes id414568915 l tr amp mt 12

Below is a list of the common key codes for quick reference  taken from Events h  If you need to use these keycodes in an application  you should include the Carbon framework  Objective-C   include  lt Carbon Carbon h gt  Swift  import Carbon HIToolbox You can then use the kVK ANSI A constants directly   WARNING The key constants reference physical keys on the keyboard  Their output changes if the typist is using a different keyboard layout  The letters in the constants correspond only to the U S  QWERTY keyboard layout  For example  the left ring-finger key on the homerow  QWERTY keyboard layout  gt  s  gt  kVK ANSI S  gt   quot s quot  Dvorak keyboard layout  gt  o  gt  kVK ANSI S  gt   quot o quot  Strategies for layout-agnostic conversion of keycode to string  and vice versa  are discussed here  How to convert ASCII character to CGKeyCode   From Events h         Summary        Virtual keycodes          Discussion        These constants are the virtual keycodes defined originally in       Inside Mac Volume V  pg  V-191  They identify physical keys on a       keyboard  Those constants with  quot ANSI quot  in the name are labeled       according to the key position on an ANSI-standard US keyboard        For example  kVK ANSI A indicates the virtual keycode for the key       with the letter  A  in the US keyboard layout  Other keyboard       layouts may have the  A  key label on a different physical key        in this case  pressing  A  will generate a different virtual       keycode      enum     kVK ANSI A                      0x00    kVK ANSI S
