Kirk,
It's very easy to copy and paste a channel (or group of channels) by dragging the curser down the far-left column to highlight the channel(s) you want to move. For example, if you want to move channels 5, 6 and 7 just click on the 5 and drag the curser down to 7 so that all three are highlighted. Then you can right-click (or control-c) and copy those three channels. Once they're copied, you can click on the new channel number where you like to paste/move them.
