If the leader gets to kedusha on Shabbat or Jewish festival morning and you are saying the amida, you must:

• Pause until the leader has finished the blessing after kedusha (ha'el—or ha'melech—ha'kadosh), and then

• Resume your amida.

During birkat cohanim, you must:

• Pause in your amida until the end of birkat cohanim.

EXCEPTION Do not pause, even if the leader says kaddish or kedusha, if doing so will delay you past the fourth hour.
