expression Required. A variable that represents a Selection object.
This example inserts a style separator after every paragraph formatted with the built-in "Heading 4" style.
The paragraph count is inside the Do...Loop because when Word inserts the style separator, the two paragraphs become one paragraph, so the paragraph count for the document changes as the procedure runs.
Sub InlineHeading() Dim intCount As Integer Dim intParaCount As Integer intCount = 1 With ActiveDocument Do 'Look for all paragraphs formatted with "Heading 4" style If .Paragraphs(Index:=intCount).Style = "Heading 4" Then .Paragraphs(Index:=intCount).Range.Select 'Insert a style separator if paragraph 'is formatted with a "Heading 4" style Selection.InsertStyleSeparator End If intCount = intCount + 1 intParaCount = .Paragraphs.Count Loop Until intCount = intParaCount End With End Sub
