I'm trying to find some VBA code to automatically check the Distinguish Style Source check box at the bottom of the Reveal Formatting Task pane in Word 2010.

While I can open the Reveal Formatting pane without a problem, I cannot find the command for this checkbox. In trying to record the steps, I only get the command to open the task pane.

Anyone know how to do this? Or if you know of a GPO setting or RegHack I could do instead, that would be fine as well.
