CommandBarButton.Priority Property (Office)
Gets or sets the priority of a CommandBarButton control. A control's priority determines whether the control can be dropped from a docked command bar if the command bar controls can't fit in a single row. Controls that can't fit in a single row drop off command bars from right to left. Read/write.
The use of CommandBars in some Microsoft Office applications has been superseded by the new ribbon component of the Microsoft Office Fluent user interface. For more information, search Help for the keyword "ribbon."
