In the Excel 2007 VBA Programmer's Reference (by John Green, Stephen Bullen,
Rob Bovey and Michael Alexander), they state:
-----
"As well as being able to retrieve the state information, you can also click
any built-in control using the new ComandBars.ExecuteMso method. This is
extremely useful for triggering those actions that dont have an object model
equivalent€”such as putting the user in drawing mode to draw a text box on a
sheet:"

Application.CommandBars.ExecuteMso €œTextBoxInsertExcel€�
-----

While the above works, when I try to use this method with a gallery control,
like:

Application.CommandBars.ExecuteMso "CellStylesGallery"

I expect either the book is wrong (i.e., the method does not apply to "any
built-in control"), or there is some syntax I have wrong in applying this.
Can anyone advise how to make this work?
