Adds the default outline-numbering scheme to the paragraphs in the range for the specified ListFormat object. If the paragraphs are already formatted as an outline-numbered list, this method removes the numbers and formatting.
expression.ApplyOutlineNumberDefault(DefaultListBehavior)
expression Required. An expression that returns a ListFormat object.
DefaultListBehavior Optional Variant. Sets a value that specifies whether Microsoft Word uses new Web-oriented formatting for better list display. Can be either of the following constants: wdWord8ListBehavior (use formatting compatible with Microsoft Word 97) or wdWord9ListBehavior (use Web-oriented formatting). For compatibility reasons, the default constant is wdWord8ListBehavior, but in new procedures you should use wdWord9ListBehavior to take advantage of improved Web-oriented formatting with respect to indenting and multilevel lists.
Remarks
This method doesn't remove built-in heading styles that have been applied to paragraphs.
Example
This example adds outline numbering to the paragraphs in the selection. If the selection is already an outline-numbered list, the example removes the numbers and formatting.
Selection.Range.ListFormat.ApplyOutlineNumberDefault
This example sets the variable myRange to include paragraphs three through six of the active document, and then it checks to see whether the range contains list formatting. If there's no list formatting, the default outline-numbered list format is applied.
Set myDoc = ActiveDocument
Set myRange = myDoc.Range( _
Start:= myDoc.Paragraphs(3).Range.Start, _
End:=myDoc.Paragraphs(6).Range.End)
If myRange.ListFormat.ListType = wdListNoNumbering Then
myRange.ListFormat.ApplyOutlineNumberDefault
End If
