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?
Matt B.
The more canonical reference is in <HIToolbox/Events.h>:
/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/Headers/Events.h
In newer Versions of MacOS the "Events.h" moved to here:
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/Headers/Events.h
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 <Carbon/Carbon.h>
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 > s > kVK_ANSI_S > "s"Dvorak keyboard layout > o > kVK_ANSI_S > "o"
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 "ANSI" 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.
