The new object will appear in a separate window.
Empty objects show up as normal text, rather than boldface.
One shortcomming of ACeDB is that there is no simple way to change the order of items added to an object. Plan carefully before you enter items. If you have to change the order, rename the existing pathway object to some temporary name, can create a new pathway object with the original pathway name. Then copy the enzymes into the new object in the correct order. It is usually best to change only one model at a time if at all possible, to avoid confusion.
