You can raise or lower text from its baseline.
Select the text you want to raise or lower, or click where you want to type new text.
To create a subscript or superscript that has a smaller font size than the text it accompanies, choose Format > Font > Baseline > Subscript. Or choose Format > Font > Baseline > Superscript.
To raise or lower text relative to the other text on the same line, choose Raise or Lower from the Baseline submenu.
To restore text to the same baseline as the body text, choose Use Default from the Baseline submenu.
To specify a precise amount to raise or lower text, use the Text inspector. Click Inspector in the toolbar, click Text, click More, and then use the Baseline Shift controls.
You can add Subscript and Superscript icons to the toolbar. Choose View > Customize Toolbar, drag the icons to the toolbar, and then click Done.
