"Compare" on the toolbar of the details or the properties of a row shows the properties of several objects of the same kind side by side. It needs the right to compare contents. The properties are compared as follows: - Tick two or more objects of the same kind in the tree. - Choose "Compare" on the toolbar. The window "Compare Properties" opens. The first column, "Natural Key", names each property. Every other column holds one object, headed by its natural key, and is compared with the first object: the changed characters are marked blue and underlined for a change, red and struck through for a deletion and green and bold for an insertion, and a row that differs is shaded. "Only Show Differences", ticked when the window opens, hides the properties that are equal. "Size To Fit" sizes the columns to their content.
