+		[b]Example:[/b] Capture the [kbd]Ctrl + S[/kbd] shortcut using a [Shortcut] resource:
+		[codeblock]
+		var save_shortcut = Shortcut.new()
+		func _ready() -&gt; void:
+			var key_event = InputEventKey.new()
+			key_event.keycode = KEY_S
+			key_event.ctrl_pressed = true
+			key_event.command_or_control_autoremap = true # Swaps ctrl for Command on Mac.
+			save_shortcut.set_events([key_event])
+
+		func _input(event) -&gt; void:
+			if save_shortcut.matches_event(event) and event.is_pressed() and not event.is_echo():
