I have seen several people mention the alternate Bb key, is this the key used by your right hand index finger? Is it by the c natural key? If so, that would be great as I hate using the thumb key and this alternate Bb key seems to be the same fingering as a saxophone (which means I could probably pick up it a lot faster).
Yes, that’s what it is. I like it a lot. I don’t confuse it with the C natural key.
