CE59 and VX-4204

One of my clients has a VX-4204 mobile in his EMS fly car. I have the software and cable and am able to read and write to the radio just fine. I was able to add new channels and modify existing ones as needed; frequency and pl changes, alpha tag, and so on. But what I can not find is how to change the sequence of the channels. For example, if I enter a new channel, say 16, but want to move it up to 8, how do I do that? I've tried all kinds of key presses and F keys with zero results.



I suspect this is something simple, but there's nothing in the help file that I can find on this and programming manuals don't seem to want to be found on google searches.
