Use the Field tool to control the size, shape, and position of boxes text goes into. Background fields are shared by every card that uses that background. Card fields appear on individual cards.
• To create a field for a single card, go to the card you want to create the card field on. To create a background field, choose Background from the Edit menu.
• Choose New Field from the Objects menu or hold down the Command key while you drag diagonally to create the field.
