You use the Paragraph panel (Window > Type > Paragraph) to change the formatting of columns and paragraphs. When type is selected or when the Type tool is active, you can also use options in the Control panel to format paragraphs.

By default, only the most commonly-used options in the Paragraph panel are visible. To show all options, choose Show Options from the panel menu. Alternatively, click the double triangle on the panel’s tab to cycle through the display sizes.
