Creating a New Slot
A new slot is created with a generic name, such as newspaper_Slot_1. There are three ways to create a slot:
By clicking the Create Slot Slot button in the Slot pane of the Slots Tab. This creates a slot, but does not assign it to any class. The slot can later be attached to one or more classes.
By right-clicking in the Slot Browser in the Slots Tab and selecting Create slot from the Slot menu. This is identical to the previous operation.
By selecting a class in the Classes tab and then clicking the Create Slot button in the Template Slots pane. This creates a slot and attaches it to the selected class.
You can use the Slot Editor to edit the properties of the slot.
