ListFormat.ApplyNumberDefault (Word)

Adds the default numbering scheme to the paragraphs in the range for the specified ListFormat object.

If the paragraphs are already formatted as a numbered list, this method removes the numbers and formatting.

ApplyNumberDefault (DefaultListBehavior)

DefaultListBehavior: 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.
