This example adds a slide with two text columns to the active presentation, sets a left-aligned tab stop for the title on the new slide, aligns the title box to the left, and assigns title text utilizing the tab stop just created.
With Application.ActivePresentation.Slides _
.Add(2, ppLayoutTwoColumnText).Shapes
With .Title.TextFrame
With .Ruler
.Levels(1).FirstMargin = 0
.TabStops.Add ppTabStopLeft, 310
End With
.TextRange.ParagraphFormat.Alignment = ppAlignLeft
.TextRange = "first column" + Chr(9) + "second column"
End With
End With
