(1.16) how to bind a key?

[WaromiV]

I want the program to write to the console if I press the "O" button and when I press it again it will write another text. How to do that?

?

private static final KeyBinding toggle = new KeyBinding("encrypt.key.toggle", 79, "key.categories.encrypt");

private static final KeyBinding toggle = new KeyBinding("encrypt.key.toggle", 79, "key.categories.encrypt");

private static final Logger LOGGER = LogManager.getLogger();
private static Boolean toggled = false;
private void setup(final FMLCommonSetupEvent event) {
    ClientRegistry.registerKeyBinding(toggle);
}

@SubscribeEvent
public static void onClientTickEvent(final TickEvent.ClientTickEvent event) {
    if (event.phase != TickEvent.Phase.END) return;
    if (toggle.isPressed()) {
        if (toggled) {
            toggled = false;
            LOGGER.info("off");
        }
        else{
            toggled = true;
            LOGGER.info("on");
        }
