Where can I find a list of Mac virtual key codes?
提问by Nick Moore
I'm using CGEventCreateKeyboardEventand need to know what CGKeyCodevalues to use.
我正在使用CGEventCreateKeyboardEvent并且需要知道CGKeyCode要使用的值。
Specifically, I am after the key code for the Commandkey. The docs give examples for other keys: zis 6, shiftis 56.
具体来说，我在寻找Command钥匙的钥匙代码。文档给出了其他键的示例：zis 6、shiftis 56。
There must be a list of Mac virtual keycodes somewhere?

The more canonical reference is in <HIToolbox/Events.h>:
更规范的参考在<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:
在较新版本的 MacOS 中，“Events.h”移至此处：
/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.
以下是用于快速参考的常用键代码列表，摘自Events.h.
If you need to use these keycodes in an application, you should include the Carbon framework:
如果您需要在应用程序中使用这些键码，您应该包含 Carbon 框架：
Objective-C:#include <Carbon/Carbon.h>
目标-C：#include <Carbon/Carbon.h>
Swift:import Carbon.HIToolbox
迅速：import Carbon.HIToolbox
You can then use the kVK_ANSI_Aconstants directly.
然后您可以kVK_ANSI_A直接使用常量。
WARNING
警告
The key constants reference physical keyson 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.
键常量引用键盘上的物理键。如果打字员使用不同的键盘布局，它们的输出会发生变化。常量中的字母仅对应于美国 QWERTY 键盘布局。
For example, the left ring-finger key on the homerow:
例如，homerow 上的左无名指键：
QWERTY keyboard layout> s> kVK_ANSI_S> "s"Dvorak keyboard layout> o> kVK_ANSI_S> "o"
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:

/*
* 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.

Here are the all keycodes.
这是所有的键码。
Here is a table with some keycodes for the three platforms. It is based on a US Extended keyboard layout.

Or, there is an app in the Mac App Store named "Key Codes". Download it to see the keycodes of the keys you press.

In addition to the keycodes supplied in other answers, there are also "usage IDs" used for key remapping in the newer APIs introduced in macOS Sierra:

Here's some prebuilt Objective-C dictionaries if anyone wants to type ansi characters:
如果有人想输入 ansi 字符，这里有一些预先构建的 Objective-C 词典：
