Selection.RtlRun (Word)

Sets the reading order and alignment of the specified run to right-to-left.

For the specified run, this method sets the reading order to right-to-left. If a paragraph in the run with a left-to-right reading order is also left-aligned, this method reverses its reading order and sets its paragraph alignment to right-aligned. Use the ReadingOrder property to change the reading order without affecting paragraph alignment.

If Selection.Style <> "Normal" Then _
