Objects

Objects that make up your scene are listed in the object browser. The name of each object (which, of course, you can change) appears as the first item in each row, followed by a small icon (known as the Object Tag) which represents what sort of object it is. There may be others following the initial Object Tag.

Tags

Tags are used to extend the properties of objects. You can add UV coordinates to an objects for example with the UV Tag.

To add a tag to an object you just select the object in the object browser and then choose the desired tag from the tag menu in the toolbar. The tag should appear on the rightmost side of the selected object. To modify the properties of the tag, just click on the tag icon. The properties of the tag should then appear in the property editor.
