Use the Object Compare window to view any two objects of the same type, whether or not they are variations of the same object.
To compare two topics or objects:
- Select the two objects in the Library Explorer, using either the folder list or the search list.
- Right-click and then choose Compare. Use the Property Sheet or Preview options below the window's header bar to view the changes made to the object. Option 1 shows the object properties, option 2 shows the content preview (depending on the type of object selected).
