TOGA
For takeoff applies fmc thrust setting, and FD guidance,
For approach gives reduced go around thrust giving 1000-2000fpm RoC with first press, or full Ga thrust with second press, and gives go around FD guidance
During windshear pressing toga initiates windshear escape maneuver (different than go around mode)
A/T off, on approach pressing toga will give you go around FD even with oei landing.

same on 737 actually, indeed nice feature
