To duplicate constraints:

1. Right-click a constraint in the Scene browser and select Duplicate from the contextual menu.

   The new, cloned constraint is added at the end of the Scene browser’s Constraints folder. Constraints can be copied into different Constraints folders.

   The new constraint is given the same name as the original, plus a sequential number. For example, if your constraint is called “Arm”, the duplicate constraints are called “Arm1”, “Arm2”, and so on.

2. Rename a Constraints folder by right-clicking it and selecting Rename from the contextual menu.
