We use 1500ft AGL as standard and only if required by other local procedures use other altitudes. For example in ZRH we use an acceleration height of 3000ft with a thrust reduction at 1500.
It is programmed in the takeoff page 2 and VNAV automaticly moves the speed bug up to the next relevant speed, thrust "reduction" is programmed there as well. Both thrust reduction and acceleration are programmed for AEO and OEI, airplane is 737NG.
