Since a tangent is a vector, it has both a direction and a length. By default, each key's in and out tangents are locked together; both tangents will rotate and scale equally. When the tangents are unlocked, they can rotate and scale independently of each other. To change the lengths of the tangents, the curve must be turned into a weighted curve and the key's weight locking must be turned off. page 167, paragraph 4, line 11 The key's value is scaled by half.

It is very important that the complete path to the children be used. Some of the children have the same name so aren't unique and when used in later statements would cause problems. In fact Maya would complain that the node name wasn't unique.
