represents the path of the object up the card to the card name.

card. You may wish to resize the Output and Rule columns on the output card to 
view the map rules.

The columns on the output cards may also be resized. 
To resize the Output and Rule columns 
1  Position the cursor at top of the column until the splitter appears. 
2  Drag the splitter until the column is the desired size.
