Hi anon125,
To quickly bring up the "Regist Bank Edit" display (for naming the Registrations on the 8 buttons), press the [Direct Access] button and then one of the [Regist Bank +/-] buttons.
To quickly call up the "Regist Bank Information" display, press the [Direct Access] button and then ...
- one of the Reg buttons [1] - [4] (= Regist Bank Information, "Voice" page) or
- one of the Reg buttons [5] - [8] (= Regist Bank Information, "Style" page).
(This information can be found in the "Direct Access Chart" in the SX900 Owner's Manual, pages 113/114.)
For more information on the Regist Bank Edit and Regist Bank Information displays, see the SX900 Owner's Manual, page 89.
Hope this helps!
Best regards,
Chris
