Set a range to the selection and process the paragraphs in the range e.g.
Code:
Sub Macro2()
Dim oPara As Paragraph
Dim oRng As Range, oSel As Range
Set oSel = Selection.Range
For Each oPara In oSel.Paragraphs
If oPara.Style Like "List*" Then
Set oRng = oPara.Range
oRng.Collapse 1
oRng.MoveEndUntil Chr(32)
oRng.End = oRng.End + 1
oRng.Text = ""
End If
Next oPara
lbl_Exit:
Set oPara = Nothing
Set oRng = Nothing
Set oSel = Nothing
Exit Sub
End Sub
