You use the Character panel (Window > Type > Character) to apply options for formatting individual characters in your documents. When type is selected or when the Type tool is active, you can also use options in the Control panel to format characters. You can find many of these same controls and options in the Control panel when your type is selected.

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