You can increase or decrease the amount of space between characters.
First select the text or a text box containing text you want to change.
Click Inspector in the toolbar, click the Text button, and then click Text. Drag the Character slider or specify a percentage in the Character field to achieve the spacing you want.
Choose Format > Font > Tracking and choose an option from the submenu to tighten or loosen the text spacing by increments. Repeat until you’ve achieved the look you want.
