how does one do hechi kedusha?

Question

I am interested in two cases: 1) the congregation is davening mincha in a rush, and doing a "hechi kedusha" (btw, what is the etymology of this phrase)

2) an individual arrives late for mincha and is able to start shemona esrei with the chazzan.

In each case, should one wait until after kedusha to begin shemona esrei, or try to start with the chazzan and go along word-for-word. In the latter case, should the individual say the entire kedusha or just the standard communal responses? How should he conclude the beracha?

Answer 1

I've always heard it as "heicha kedusha"; not sure what the etymology is.

Need sources, but off the top of my head here:

1.) Heicha kedusha:

The standard practice is listed as:

A. Ideally, listen to the chazan complete Kedusha, and then start your own Shmoneh Esrei from the beginning.
B. If you're really in a rush, daven along silently with the chazan from the beginning, then everyone continues silently from Ata Chonen.

Students of Rabbi Joseph Dov Soloveitchik (and I believe most Briskers of other influence as well) feel that B is the correct way to do it in all situations.

2.) If I recall, the guidance is to say everything exactly as the chazan does, including his lines in kedusha, the "l'dor vador" conclusion (in nusach Ashkenaz), and even Birkas Kohanim.
