No - but it is a simple matter to add a toolbar button to give you that:
amount of zoom
Sub Zoom85()
ActiveWindow.View.Zoom.Percentage = 85
End Sub
or the following will toggle between 85% and 100%
Sub Toggle85()
If ActiveWindow.View.Zoom.Percentage = 100 Then
ActiveWindow.View.Zoom.Percentage = 85
Else
ActiveWindow.View.Zoom.Percentage = 100
End If
End Sub
