Codo, by this do you mean the convention I suggested earlier (first step = bad; steps 2-5 = good + key card response) or that you should bid 5m with the bad hand and the normal Minorwood response with a good hand. If you play the second of these then I strongly recommend trying out the former which I think is several orders of magnitude better.
This has worked quite well for us. It also resolves Han's excellent point that --when our first opportunity to support partner's minor is at the 4-level we want it to be an unambiguous raise without asking for keycards.
Responder gets to punt with bad, but answer keycards with good. Opener might not have really wanted specifically to ask for keys, but he gets the information anyway when responder has the good one.
However, when the first step happens to be hearts over 4D, and that is opener's suit, further discussion might be in order.
