Represents a means of navigation in a rich text item.
Creation
To create a new RichTextNavigator
object, use the createNavigator method in RichTextItem or the Navigator
property in RichTextRange.
Usage
Navigation is within elements of the
same type. You can find or get the first element of a type, the next
element of a type, and the nth element of a type. You cannot find
or get an element regardless of type.
The navigator maintains a
current position. Both find and get operations change the current
position in the rich text item.
