+	Define action + button there
+			![[Pasted image 20240713073756.png]]
+
+Next, select a button, and open Shortcut section
+	![[Pasted image 20240713073933.png]]
+		
+	Click the <empty> Shortcut field, then select New Shortcut
+	
+
+The `Shortcut` resource takes an array of inputs as its data because in case you'd want to trigger the same button with multiple different inputs or input actions.

+Click on the created InputEventAction to expand it.

+Set action to advance_text ( The action we created in the very first screenshot of this page)
+
+	![[Pasted image 20240713080125.png]]
+
+Now all input defined for advance_text action will trigger the button.

+
+
+Disabling button until tween finished
+```python
+func show_text() -> void:
+	# We first extract data for the current dialogue item and apply it to the UI
+	# elements.
+	# ...
+	next_button.disabled = true
+	tween.finished.connect(func() -> void:
+		next_button.disabled = false
+	)
+```
+
+
+
+
+Note to self: It seems to be possible to connect an event to more than 1 function. Here the full function from the tutorial. Note the tween.connect re-use
+
+```python
+func show_text() -> void:
+	# We first extract data for the current dialogue item and apply it to the UI
+	# elements.
+	var current_item := dialogue_items[current_item_index]
+	rich_text_label.text = current_item["text"]
+	expression_texture_rect.texture = current_item["expression"]
+	body.texture = current_item["character"]
+
+	# We then hide the text and animate it appearing.
+	rich_text_label.visible_ratio = 0.0
+	var tween := create_tween()
+	var text_appearing_duration: float = current_item["text"].length() / 30.0
+	tween.tween_property(rich_text_label, "visible_ratio", 1.0, text_appearing_duration)
+
+	# We randomize the audio playback's start time to make it sound different
+	# every time and play the sound until the text finishes displaying.
+	var sound_max_length := audio_stream_player.stream.get_length() - text_appearing_duration
+	var sound_start_position := randf() * sound_max_length
+	audio_stream_player.play(sound_start_position)
+	tween.finished.connect(audio_stream_player.stop)
+
+	# We animate the character sliding in.
+	slide_in()
+
+	# Finally, we disable the next button until the text finishes displaying.
+	next_button.disabled = true
+	tween.finished.connect(func() -> void:
+		next_button.disabled = false
+	)
+
