When you query a feature in the View window, information about that feature is shown in the Feature Information window. This information includes feature type, attributes (both user and format attributes), coordinate system, and geometry details.
You can use the Display Control to query multiple features, and cycle through each one using the Features Selected tool at the top.
The Attributes node lists all FME, format, and user-defined attributes and values that are part of the currently selected feature.
The Geometry node lists all geometric information for the currently selected feature.
Note: For more information on the Feature Information window, see Understanding the Feature Information Window.
