There are two ways to raise or lower text in relation to adjacent text:
Make characters superscript or subscript: This moves the characters higher or lower and makes them smaller, which is useful for adding copyright or trademark symbols, for example.
Adjust the baseline shift: This lets you fine-tune text placement without changing text size.
Select one or more characters you want to raise or lower.
Click the Text tab at the top of the sidebar on the right.
If you don’t see a sidebar, or the sidebar doesn’t have a Text tab, click
in the toolbar.
Click the Style button near the top of the sidebar.
In the Font section, click
, click the Baseline pop-up menu, then choose Superscript or Subscript.

If you want to continue typing regular text right after the superscript or subscript, click directly after the superscript or subscript character, click
in the sidebar, click the Baseline pop-up menu, then choose Default.
You can also use keyboard shortcuts to quickly apply superscript or subscript to selected text. For superscript, press Control-Shift-Command-Plus Sign (+). For subscript, press Control-Command-Minus Sign (-).
If you want to make text higher or lower than the text next to it without changing its size, adjust its baseline shift.
Select one or more characters you want to raise or lower.

, then click the arrows next to the Baseline Shift value to raise or lower the selected text.

You can add buttons to the Keynote toolbar to quickly apply superscript and subscript to selected text. The buttons appear in the toolbar of every Keynote presentation.

Note: The View menu in the Keynote toolbar doesn’t have this option.
Drag the Superscript and Subscript buttons to the toolbar.
Click Done.
To remove the buttons, choose View > Customize Toolbar, then drag the buttons away from the toolbar until they disappear.
