All resources of the selected type (see Resource Type selection) in the current book are listed in this area of the Resource Finder window.
If the Limit To Resources Used box is checked, then only resources that are currently being used by an object in the book are listed. Also, for bitmap resources, you can limit display to particular graphic formats with the Bitmap Types to Display check boxes. You can use the Resource Finder sort columns to sort the displayed resources by either name, id, or times used.
To find all objects in your book that use a specific resource, select the resource and click on the Search For Objects ... button.
