In graphics mode, each object is represented by a box that shows the value of a single attribute. By default, you see the value of the Object Short Text, but you can show a different attribute value. If the object does not have Object Short Text, you see in order of priority, the Object Heading, or Object Text, or Object Identifier.
The current object has a pink border, and is always visible on your screen. As you navigate around the module, the display changes to keep the current object near the center of your screen. On a large screen, the objects in the center of the screen are magnified, as if you are looking through a fish-eye lens.
A red square or triangle indicates that there are child objects that are hidden because they do not fit on your screen. Click the red square or triangle to see the hidden objects. A red square means that a single object tree is hidden. A red triangle means that two or more object trees are hidden.
