Access OpenType Font Features
OpenType fonts (.otf) often have special features, such as swashes and alternate characters, that are accessible in any app that uses the OS X font panel, including Pages and TextEdit. To access them, type and select your text, press Command-T to open the font panel, and then choose Typography from the Actions pop-up menu. That shows the Typography panel, where you can toggle available options for the font and characters you've selected.
