I'm not sure the practical usage of this command, but basically, you can control where you INSERT the current TYPE object into the TYPE collection. When you create a new Type object with the NEW command, it is automatically appended to the END of the collection. Using INSERT along with BEFORE and AFTER (and electively FIRST and LAST) to put the Type object exactly where you want it. Sounds confusing - and chances are likely you'll never need this ability. But its here if you need it. Check the example.
