types of text boxes
Numbers has two types of text boxes:
Two-handled: A two-handled text box displays two selection handles (blue dots) when it’s selected, and resizes automatically when you add text. Text boxes you add using are two-handled text boxes.
Eight-handled: An eight-handled text box displays eight selection handles (blue dots) when it’s selected. These text boxes don’t resize automatically when you add text. Most of the placeholder text boxes that come with a template are eight-handled text boxes.
Note: You can’t add drop caps to two-handled text boxes.
