This gets rid of EVERY bracket in that style - including ones that the earlier macro didn't put in.
Code:
Sub RemoveBracketsUPDATED()
With Selection.Find
.ClearFormatting
.Style = ActiveDocument.Styles("Normal")
.Text = "[\(\)]{1}"
.Replacement.Text = ""
.Forward = True
.Wrap = wdFindContinue
.MatchWildcards = True
.Format = True
.Execute Replace:=wdReplaceAll
End With
End Sub
