How can I create a fraction in Word that isn't in any of the fonts I have?

This is too cool not to share. Mrs. Freeholder is working on an advanced degree, and needed to type fractions in the traditional format--numerator, horizontal line, denominator. There are fraction fonts, but she needed to be able to create them on the fly. After a bit of Googling, I found the perfect " how to" on the Microsoft Word MVP site. Way cool!
