Anyone have info on how to use FM notation to use this shortcut on the BA 2 Plus Pro.  
Most resources online seem to cater to CFA/CA methods which is confusing me regarding traditional FM notation of bonds.

The instruction manual for the BAII Plus Pro says the BOND worksheet calculates the modified duration for you. Do you mean the older BAII Plus instead?

I found it in the Guo manual!  
It was a bit tricky to find the steps since most online resources cite how to use it using CFA/CA notations.
