In Word 2013, you add superscript to individual characters from the Home tab. Although a simple format change, this can turn your writing into a stop-start process if you frequently use superscript characters, such as the squared symbol. If you prefer to keep your creative juices flowing and your fingers typing, you can also set up a keyboard shortcut for superscript characters you use regularly in Word's AutoCorrect tool.
Add Superscript to Individual Characters
Type or insert the letter, number or symbol that you want to change to superscript. For example, if you want to make an x-squared character, start by using regular letters and numbers -- so type x2 into your document.
Highlight the 2 in your text. In the Font area of the Home tab, select the Superscript button, the x-squared symbol. The button toggles on and changes color, and your number format changes to superscript.
Make sure that the cursor is to the right of the superscript number you've just formatted. Select the Superscript button again to turn it off -- it will switch back to its original color. If you don't disable it, you'll carry on typing in superscript. If you do this by mistake, highlight the characters and select the Superscript button to switch the characters back to their regular size.
Add a Superscript Shortcut in AutoCorrect
Type a 2 in your document, highlight it and select the Superscript button from the Home tab. Copy the new superscript character. Open the File tab and then Options.
Open Proofing and select AutoCorrect Options. You're going to set keys into the AutoCorrect tool and connect them to your squared symbol, so that Word inserts it automatically whenever you use the right key combination.
Select the Formatted Text button. You should see the number you copied in the box below. Type /#, without bold, in the Replace box. Make sure that the Replace Text As You Type box is checked. Select Add and then OK twice to return to your document. Now, whenever you type /#, Word should automatically insert the squared symbol.
