Abstract:

Can you find the fractions on your keyboard? If not, you’re not alone. Believe it or not, there are no designated keystrokes for fractions on a Mac. PCs offer a few (1/4, 1/2, 3/4), but they’re so well-hidden most users can’t find them anyway. Yet fractions appear fairly often in copy, so what’s a person to do? It’s too frustrating by half!
