/// input, use the individual <see cref="KeyControl"/>-type controls present on the keyboard.
/// For example, <see cref="aKey"/>. To receive text input, use the <see cref="onTextInput"/>
/// callback.
///
/// The naming/identification of keys is agnostic to keyboard layouts. This means that <see cref="aKey"/>,
/// for example, will always be the key to the right of <see cref="capsLockKey"/> regardless of where
/// 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
