Certain time and keyframe functions on controllers can be called on any 3ds Max object or collection of 3ds Max objects.
If called in this way, they apply recursively to all the nested controllers within that object and on any on sub-objects and sub-controllers within those objects.
In this way, they work in a manner similar to the object-level tracks in the 3ds Max Track View that allow you to manipulate keys and time for all the sub-objects and sub-controllers within them.
The time and controller functions that work this way are:
deleteTime reverseTime scaleTime insertTime setTimeRange addNewKey deleteKeys selectKeys deselectKeys moveKeys mapKeys sortKeys reduceKeys addEaseCurve deleteEaseCurve setBeforeORT setAfterORT enableORTs
The above functions can be called on any 3ds Max object collection (such as a wild-card pathname or object set or array of objects ) and will recursively apply to all animation within those objects.
