Missed approach:
From an aircraft perspective - Single push TOGA switches = leisurely 2000 fpm clb, (thr toga toga) if LNAV available it will auto engage at 50 RA or above (thr lnav toga). VNAV is available at 400 baro but whether or not you can use it is up to your company.
From a human perspective - What Uplinker said..
BTW, If you select toga at less than 2 ra (when rollout is engaged) then nothing will happen so its manual thrust only
// edited to add ra and baro.. . //
