You can use Copy and Paste to copy object and modifier tracks, controllers, objects, and containers, depending on what you are working on.
Not all tracks can be copied and pasted. The basic restrictions for using Copy and Paste in Track View are:
Only a single selected item can be copied.
A copied item can only be pasted into another item of the same type.
A copied item can be pasted into a selection of multiple items only if all of the items are of the same type.
Procedure
To copy and paste a modifier:
In the Track View Hierarchy, select a modifier track.
On the Track View toolbar, click the Copy Controller button.
Select the object track for an object in the Track View Hierarchy.
Click the Paste Controller button.
The Paste dialog diplays.
Set the options in the Paste dialog, and click OK.
The pasted modifier is inserted above the object track you selected. Note that it does not replace any of the tracks in the target object.
