In building games with any language, there will be a loop to handle the key events. In case of crossterm, it’s event::read:

if poll(Duration::from_millis(10))? {
    let event = read()?;
    match event {
        Event::Key(KeyEvent {
            code,
            state: _,
            kind,
            modifiers: _,
        }) => {
            if kind == KeyEventKind::Press {
                let mut tetromino = self.current_tetromino.clone();
                match code {
                    KeyCode::Char('h') | KeyCode::Left => {
                        tetromino.move_left(self, stdout)?;
                        self.current_tetromino = tetromino;
                    }
