The Airbus thrustlevers has three detents, so to speak. TOGA is at the most forward TLA (Thrust Lever Angle.) There is Flex/MCT and then there is CLB.
For a max power T/Off or a go a round, TOGA is used. For a normal takeoff Flex/MCT is used. Flex means using less than max power, you would put the assumed temperature in the MCDU and the computer would calculate the thrust output required. The climb detent is used for, obviously, climb power, but this is also the detent used for cruise and descent.
Furthermore, this detent is also used for landing, unless A/THR is selected off.
