Domino's Button Numbers

I'm trying to build some Click Castsequences for my roommate who uses Domino's.
Is there any way to figure out the name of the buttons within Domino's?

/Click MultiBarBottomRightButton4 does not work.

Unfortunately, there are only 12 posts which search shows for "Domino", and none are relevant.
Too many hits for +Click +Sequence.

paste the following into chat, hit return when hovering mouse over the button you want.

/script DEFAULT_CHAT_FRAME:AddMessage( GetMouseFocus():GetName() );

Thanks.
