We did a climb with only the FD's on (A/P OFF) and I remember that levelling off the FMA annunciated ALT CRZ and so the FMS went in the CRZ phase (as I stated in the first post). After the level off we decided to switch off the FD's.
So i wouldn't be surprised (after what has been said in all these posts), that if we would have also switched off the FD's, during climb, the FMS would have remained in the CLB phase even after the level off.

What I've really learned is that the ALT SELECT Knob, with AP and FD's OFF, has no effect on the FMS and (as stated before) even changing the altitude in the mcdu, has no effect on the FMS flight phase.
