fration command in quark

can anyone tell me if there is an actual key command to make fractions in quark? (i know about going under type style, but was wondering if there was a key command that i could use just the keyboard for.) thanks! ~kate

from Quark Express site:

Problem 1:
I want to create the fraction “two and a half.” But, when I type in 21/2 and apply the Make Fraction type style by highlighting the 1/2, it applies the Fraction style to the whole numeric string: i.e., 21/2. (21 halves)

Explanation 1:
This is not considered a bug; in order to show 2 1/2 correctly, there must be a space between the number and the fraction.
