-/// Key codes for keys that are independent of keyboard layout.
+/// Constants for the virtual key codes
 ///
-/// [Ref](https://github.com/phracker/MacOSX-SDKs/blob/master/MacOSX10.13.sdk/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/Headers/Events.h)
+/// These constants are the virtual keycodes defined originally in
+/// Inside Mac Volume V, pg. V-191. They identify physical keys on a
+/// keyboard. The struct contains the values of the ANSIKeyCode,
+/// KeyCode, ISOKeyCode and JISKeyCode of the original Carbon headers.
+///
+/// Those constants with "ANSI" in the name are labeled
+/// according to the key position on an ANSI-standard US keyboard.
+/// For example, `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. Constants with the 'JIS_' or 'ISO_' prefix behave
+/// analogously. Keys without a prefix are independent of the
+/// keyboard layout.
