Represents a key on a keyboard being pressed or released.

Description
-----------

An input event for keys on a keyboard. Supports key presses, key releases and :ref:`echo<class_InputEventKey_property_echo>` events. It can also be received in :ref:`Node._unhandled_key_input<class_Node_private_method__unhandled_key_input>`.

\ **Note:** Events received from the keyboard usually have all properties set. Event mappings should have only one of the :ref:`keycode<class_InputEventKey_property_keycode>`, :ref:`physical_keycode<class_InputEventKey_property_physical_keycode>` or :ref:`unicode<class_InputEventKey_property_unicode>` set.

When events are compared, properties are checked in the following priority - :ref:`keycode<class_InputEventKey_property_keycode>`, :ref:`physical_keycode<class_InputEventKey_property_physical_keycode>` and :ref:`unicode<class_InputEventKey_property_unicode>`. Events with the first matching value will be considered equal.

Property Descriptions
---------------------

.. _class_InputEventKey_property_echo:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **echo** = ``false``

.. rst-class:: classref-property-setget

- void **set_echo** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_echo** **(** **)**

If ``true``, the key was already pressed before this event. It means the user is holding the key down.

.. rst-class:: classref-item-separator

.. _class_InputEventKey_property_key_label:

.. rst-class:: classref-property

:ref:`Key<enum_@GlobalScope_Key>` **key_label** = ``0``

.. rst-class:: classref-property-setget

- void **set_key_label** **(** :ref:`Key<enum_@GlobalScope_Key>` value **)**
- :ref:`Key<enum_@GlobalScope_Key>` **get_key_label** **(** **)**

Represents the localized label printed on the key in the current keyboard layout, which corresponds to one of the :ref:`Key<enum_@GlobalScope_Key>` constants or any valid Unicode character.

For keyboard layouts with a single label on the key, it is equivalent to :ref:`keycode<class_InputEventKey_property_keycode>`.

To get a human-readable representation of the **InputEventKey**, use ``OS.get_keycode_string(event.key_label)`` where ``event`` is the **InputEventKey**.

        | Q   | | Q   | - "Q" - keycode
        |   Й | |  ض | - "Й" and "ض" - key_label
        +-----+ +-----+

- void **set_keycode** **(** :ref:`Key<enum_@GlobalScope_Key>` value **)**
- :ref:`Key<enum_@GlobalScope_Key>` **get_keycode** **(** **)**

Latin label printed on the key in the current keyboard layout, which corresponds to one of the :ref:`Key<enum_@GlobalScope_Key>` constants.

To get a human-readable representation of the **InputEventKey**, use ``OS.get_keycode_string(event.keycode)`` where ``event`` is the **InputEventKey**.

::

        +-----+ +-----+
        | Q   | | Q   | - "Q" - keycode
        |   Й | |  ض | - "Й" and "ض" - key_label

- void **set_physical_keycode** **(** :ref:`Key<enum_@GlobalScope_Key>` value **)**
- :ref:`Key<enum_@GlobalScope_Key>` **get_physical_keycode** **(** **)**

Represents the physical location of a key on the 101/102-key US QWERTY keyboard, which corresponds to one of the :ref:`Key<enum_@GlobalScope_Key>` constants.

To get a human-readable representation of the **InputEventKey**, use :ref:`OS.get_keycode_string<class_OS_method_get_keycode_string>` in combination with :ref:`DisplayServer.keyboard_get_keycode_from_physical<class_DisplayServer_method_keyboard_get_keycode_from_physical>`:


.. tabs::

 .. code-tab:: gdscript

    func _input(event):
        if event is InputEventKey:
            var keycode = DisplayServer.keyboard_get_keycode_from_physical(event.physical_keycode)
            print(OS.get_keycode_string(keycode))

 .. code-tab:: csharp

    public override void _Input(InputEvent @event)
    {
        if (@event is InputEventKey inputEventKey)
        {
            var keycode = DisplayServer.KeyboardGetKeycodeFromPhysical(inputEventKey.PhysicalKeycode);
            GD.Print(OS.GetKeycodeString(keycode));
        }
    }



.. rst-class:: classref-item-separator

----

.. _class_InputEventKey_property_pressed:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **pressed** = ``false``

.. rst-class:: classref-property-setget

- void **set_pressed** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_pressed** **(** **)**

If ``true``, the key's state is pressed. If ``false``, the key's state is released.

.. rst-class:: classref-item-separator

----

.. _class_InputEventKey_property_unicode:

.. rst-class:: classref-property

:ref:`int<class_int>` **unicode** = ``0``

.. rst-class:: classref-property-setget

- void **set_unicode** **(** :ref:`int<class_int>` value **)**
- :ref:`int<class_int>` **get_unicode** **(** **)**

The key Unicode character code (when relevant), shifted by modifier keys. Unicode character codes for composite characters and complex scripts may not be available unless IME input mode is active. See :ref:`Window.set_ime_active<class_Window_method_set_ime_active>` for more information.
