Just a question I've never been able to find a concrete answer to. At what point does a chazzan take his three steps back at the end of chazaras hashatz? Would it be while/after saying "Yihyu l'ratzon"? Or does he keep his feet together until the end of Kaddish Shalem (for example, on Shabbos shacharis/mussaf)?
What about when there's something in between the end of chazaras hashatz and kaddish, like avinu malkeinu (for example, on rosh hashana shacharis)?
