ToolsBulletsNumbers

WordBasic allows you to remove all manually typed numbering from a selection using the old Word 2 command:

WordBasic.ToolsBulletsNumbers Replace:=0, Type:=1, Remove:=1

This is particularly useful for removing manually typed numbering from Headings in a document you have been emailed, prior to applying List Numbering. If you go into Outline View, set the Heading Level to the number of levels you need to remove the typed numbering from, and run the above line, it will just remove numbering from those Headings and will leave the body text alone.
