This is an effect so regular Text access with the Text inspector is not available. Font, Size, Tracking and Color options provided. This effect is designed to be used very quickly so there are not a lot of options.
Remember to Save Effects Preset to keep your favorite settings accessible (this allows you to create a custom version of this effect for future use.)
