Syntax

public class Keyboard : InputDevice, ITextInputReceiver

Remarks

Keyboards allow for both individual button input as well as text input. To receive button input, use the individual KeyControl-type controls present on the keyboard. For example, aKey. To receive text input, use the onTextInput callback.

The naming/identification of keys is agnostic to keyboard layouts. This means that aKey, for example, will always be the key to the right of capsLockKey regardless of where the current keyboard language layout puts the "a" character. This also means that having a binding to "<Keyboard>/a" on an 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 displayName property. This can also be used in bindings. "<Keyboard>/#(a)", 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 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 Key enumeration -- whether they are actually present on the physical keyboard or not. It is thus not possible to find out this way whether the underlying keyboard has certain keys or not.
