When you apply superscript, a predefined baseline shift and type size are applied to the selected text, positioning it above the normal line of type. To apply superscript:
Click the text frame to open the Text editing toolbar.
Select the part of the text, then click Superscript to position it above the normal line.
Note: If you don't select any text, the setting applies to the new text you type in the same text frame.
Save the page when you're done.
