In that case you will have to tap the space bar three times, because text (which is what spaces are) is not included in a style. Or you could ignore the spaces and apply the spaces to text in the normal style with a macro or the replace function e.g.
Code:
Sub Macro1()
Dim oPara As Paragraph
For Each oPara In ActiveDocument.Paragraphs
If oPara.Style = "Normal" Then
Do While oPara.Range.Characters(1) = Chr(32)
oPara.Range.Characters(1).Delete
Loop
oPara.Range.InsertBefore " "
End If
Next oPara
lbl_Exit:
Set oPara = Nothing
Exit Sub
End Sub
