Type Number Event key Revision Release 2021.3642 Keywords key, nativeKeyCode
Provides the key's unique integer ID assigned to it by the operating system.
This key code is not cross-platform, meaning that its numeric value for the same key will vary on different operating systems. For example, the "A" key will have key code
29 on Android and key code
65 on Windows.
On Android, the key code's value will match a
KEYCODE constant defined in Android's
KeyEvent Java class.
On Windows, the key code's value will match a "virtual key code" constant in Microsoft's
WinUser.h C/C++ file, such as
VK_RETURN. In .NET, it would match a constant in the
System.Windows.Forms.Keys enum, which provides the same key code constants defined in C/C++.
