never set one up but I think the 9650 has quite a number of buttons and you then should start with the next one.
I guess if you can't figure out how many buttons there really are, and the manual is not a great help here, then assign a button every 10 buttons and see which one works that has helped me in the past to find it.
from the Matrix
• Programmable/Contextual buttons: 15
- 4 contextual softkey buttons. Context sensitive allocation of e.g. Hold, Transfer, Conference and more.
- 3 self-labeled Appearance/Feature buttons with LED for access to 24 administered Appearances/Features at the side of the display.
- 8 Additional self-labeled Appearance/Feature buttons with LED with direct access to 2*8 Appearances/Features.
