Apps for word and text processing software that come with Mac OS X have a method for creating superscripts: an elevated font style frequently used in exponents in math functions and scientific symbols, and to refer to footnotes from the main body of a page. With slight variations, the superscript technique applies to Pages, Notes and Stickies.
Step 1: Start Pages
Start the Pages app by clicking its icon in the Dock.
Step 2: Create Blank Document
Choose a blank document and enter some text in it.
Step 3: Highlight Text
Highlight the text you want to change to superscript.
Step 4: Change Text to Superscript
Click the Format menu, select Font, click Baseline, then click Superscript. Pages converts the highlighted text to a superscript.
To use superscript in Notes, select the text you want to set to superscript. Click the Format menu, select Font, click Baseline, then click Superscript.
To use superscript in Stickies, select the text you want to set to superscript. Click the Font menu, click Baseline and select Superscript.
You can make subscripted text in much the same way as superscripts in Pages, Notes and Stickies. The first few steps are the same as described above. For the last step, select Subscript instead of Superscript.
