[Bf-committers] A way to apply transformation to all key frames?

[imagenesis at gmail.com]

Hello, I would like to move an animated object. There does not appear to be
a way to do so without applying the transformation to every relevant key.
Is there a script or a way to apply a transformation to all relevant keys?
Presumably, a workflow would look something like:

Select relevant keys in the graph editor and change their transformation
matrix by the specified amounts.

Another workflow could be:

Select all relevant objects. Hit a key to enter into key transformation
mode. Make a transformation. The transformation is applied to all the keys
for that object. Save this transformation. Then you can select other
objects that not visible in the frame on which you performed the
transformation and apply the stored transformation to the objects. This
workflow would be a further convenience.
