I think it is the same on any keyboard instrument, taking a lot practise that 
is. I have been using a Roland A-500 for a couple of years, and it is tricky as 
well, even though the touch is very good.

Relative a piano accordion, one should hold the hand ore from above and fingers 
more curved.

The piano is weighted, which forces the use of the hand, wrist, and the arm, in 
circulation at need. On a piano according that would not be needed, just using 
the fingers.

I couldn't tell for buttons, but with full scale keyboard, is normally an 
advantage with adjacent, or close together, keys. Also, one can switch fingers 
during an ornament, but I do not know if it is done on accordions.

Nice to come out of the closet. :-)
