Thank you Suzanne; I hadn't even thought about that.
In that case, Brenda, to set up an autocorrect for it, you should enter the
correct code in the replace with box. Rather than typing in the document
first - put your cursor in the replace with box and type 2122 and then press
Alt+X (Word 2002/2003) or press and hold Alt while you type 8482 on the
numeric keypad (All versions).
