Many Lucid keys provide images and web pages for Features, States and Entities, to help make an identification easier and more accurate and to provide extra information on the items in the key. For example, web pages and images attached to Features and States may help you decide which State of a Feature to choose, or provide background hints and tips on difficult features. Similarly, web pages and images attached to Entities may provide descriptions and extra information on the entities in the key, both to add to the available information and to help you choose whether an identification is correct.
By default, items in the Features and Entities panels that have images attached will be preceded by the 
icon, while items that have web pages attached will be preceded by the 
icon.
Optionally, image thumbnails can be displayed in the Features and Entities panels for items that have images attached. To display thumbnails check either or both the Feature Thumbnails 
or Entities Thumbnail 
options located on the main toolbar.
With the Image Thumbnails checked, features or entities that have images attached will be preceded by a small thumbnail of an image associated with that item.
To view a web page or image attached to an item click on its icon or thumbnail.
