---------------
The Undo tab will provide you with enough information to know that
a change has occurred. It, however, will not tell you much about
the effect of the transaction on the objects that were changed
during the transaction. "Presentation" and "logic" objects like
DTML Methods, DTML Documents, Zope Page Templates, and Script
(Python) objects support *History* for this purpose. If you know
a transaction has effected one of these objects, you can go to
that object's *History* View and look at the previous states of
the object, as shown in the figure below.

"a transaction has effected one of these objects" -> a transaction has affected one of these objects
