Instead of using the collection's item method, you can use an index to directly access an element in the collection. for example, the element returned from the collection represented by ocoll(0) is the same as the element returned by ocoll.item(0).

the controlrange collection is available as of microsoft® internet explorer 5.

oControlRange(i).style.fontFamily=event.srcElement.style.fontFamily;
