When you choose superscript, a predefined baseline shift value and type size are applied to the selected text. The superscript text is above the normal line of type. Use the following guideline to apply superscript:
1. Double-click on the text frame to open the Text editing toolbar.
2. Select the part of the text, and then click Superscript to position the selected text half a character above the normal line.
Note: If you don't select any text, the setting applies to the new text you write in the same text frame.
That's it! Don't forget to save the page when you're done.
