Grouping Pushbuttons 
You create the pushbuttons that appear in the POD on the Button tab page in POD Maintenance. If you have a large number of pushbuttons you want to make available to operators, you can group them together.
When you group pushbuttons, the POD displays a single pushbutton with a label you define. When an operator chooses this pushbutton, the POD displays a list of activities the operator can select from. When the operator chooses OK, the POD runs the activity as defined on the Button tab page.
