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.
In the Format 
sidebar, click the Style button near the top.
If the text is in a text box, table, or shape, first click the Text tab at the top of the sidebar, then click the Style button.
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 (-).
