/// <summary>
/// Enumeration of key codes.
/// </summary>
/// <remarks>
/// Named according to the US keyboard layout which is used as a reference layout.
///
/// Note:
/// Unity input system key codes and input manager key codes are designed with game controls in mind.
///
/// This means the way they are assigned is intended to preserve the location of keys on keyboards,
/// so that pressing a key in the same location on different keyboards should result in the same action
/// regardless of what is printed on a key or what current system language is set.
///
/// This means, for example, that <see cref="A"/> is always the key to the right of <see cref="CapsLock"/>,
/// regardless of which key (if any) produces the "a" character on the current keyboard layout.
///
/// Unity relies on physical hardware in the keyboards to report same USB HID "usage" for the keys in
/// the same location.This puts a practical limit on what can be achieved, because different keyboards
/// might report different data, and this is outside of Unity's control.
///
/// For this reason, you should not use key codes to read text input.
/// Instead, you should use the <see cref="Keyboard.onTextInput"/> callback.
/// The `onTextInput` callback provides you with the actual text characters which correspond
/// to the symbols printed on a keyboard, based on the end user's current system language layout.
///
/// To find the text character (if any) generated by a key according to the currently active keyboard
/// layout, use the <see cref="InputControl.displayName"/> property of <see cref="KeyControl"/>.
///
/// <example>
/// <code>
/// // Look up key by key code.
/// var aKey = Keyboard.current[Key.A];
///
/// // Find out which text is produced by the key.
/// Debug.Log($"The '{aKey.keyCode}' key produces '{aKey.displayName}' as text input");
/// </code>
/// </example>
/// </remarks>
// NOTE: Has to match up with 'KeyboardInputState::KeyCode' in native.
// NOTE: In the keyboard code, we depend on the order of the keys in the various keyboard blocks.

/// callback.
///
/// The naming/identification of keys is agnostic to keyboard layouts. This means that <see cref="aKey"/>,

/// the current keyboard language layout puts the "a" character. This also means that having a
/// binding to <c>"&lt;Keyboard&gt;/a"</c> on an <see cref="InputAction"/>, for example, will
/// bind to the same key regardless of locale -- an important feature, for example, for getting
/// stable WASD bindings.
///
/// To find what text character (if any) is produced by a key, you can use the key's <see
/// cref="InputControl.displayName"/> property. This can also be used in bindings.
/// <c>"&lt;Keyboard&gt;/#(a)"</c>, for example, will bind to the key that produces the "a"
/// character according to the currently active keyboard layout.
///
/// To find out which keyboard layout is currently active, you can use the <see cref="keyboardLayout"/>
/// property. Note that keyboard layout names are platform-dependent.
///
/// Note that keyboard devices will always have key controls added for all keys in the
