The 777 has trim switches etc just like any other boeing you find, on the stick and a lever on the pedestal. The feel is created by feedback actuators under the flt deck floor.
The FBW has methods of trimming and deals with long term and short term trimming.
The short term is normal trim switches but if the control is held off for a long period, the FBW trims the stab to the new position.
unlike the Airbuses the 777 is quite good in that you can see all the controls move, and supply feel in the various flight regimes.
Just out of interest, the 777 does have bank angle protection as well, e.g over 30 bank and the wheel will right itself with the voice shouting 'bank angle'. this can be ovverriden.
