Ah, this is probably the wrong place.
http://forums.wolflair.com/forumdisplay.php?f=62 is probably the right place to go. That said, your easiest way to implement this is to start a new file in the editor for your system, find a similar item (here, a spell of the same class-list and level), and copy it. Change the name and description, and give it a new ID, and that will generally work for you. After that, it's just refining the entry.
You may also want to check out the help file in the editor. Usually, the general topic for a system explains how to do the basics.
