The button appears in the ribbon. Not using the QAT. This is the xml I am using.
<button id="Btn99" label="Style Menu" onAction="btnNewStyleSets_Click"/>
When I click the button, nothing happens. What I don't understand is what the btnNewStyleSets_Click routine is. Is it some hidden built in procedure within Word, or do I have to write something in my VBA to display the dialog?

I use VBA a lot in Access and understand if it was in Access, I would just create a button click procedure. Not sure if I have to create the procedure in Word, or if it is some embedded procedure.
