Reply To: hearing every word of Megillah

On two occasions, I personally witnessed the grandson of Rav Avigdor Miller zatzal instruct that all the doors of his shul be locked prior to commencing krias hamegillah, and instruct congregants not to bang by Haman, or even to tap their feet on the ground AT ALL. He stands facing the baal korei and follows along with his finger pointing to every word. That is the right way to hear the megillah raboisai.
