Numbers in ribbon

Activating ribbon customization in Creo 4.0 enables numbers in ribbon. What are these numbers?

Hi Michael,

The numbers will order what are the first groups to collapse when you decrease the window. First group to decrease will be number 8, then 7... etc and you can change the numbers:

Basically it is an indicator to show which group will collapse on priority. Priority can change as per requirement. Commonly it is usefule when you are using customized UI.
