I am using Office 2003 on Windows XP.

I have a dropdown control on a custom toolbar that is populated with some
items.
I also have a button, which when the user clicks it, I would like the next
item in the drop down to become selected (like a scrolling button), so the
user can quickly scroll through the list, making each next item the item
selected in the drop down.

The user also needs to be able to access the drop down in the customary way.

Can someone please post example code to do this?

Thanks.
