When I started this file, I selected how many devices I wanted. Then, each device got a theme. I then assigned those devices their appropriate IR commands from the IR DB in the initial New File Window.

When I'm going to program the device, I don't know where to drag and drop these "assigned codes" onto my Macro. I only see the IR Navigator in the right hand dock. I would have expected the transporter to show me all codes that are possible. Instead, I'm seeing "Hard Buttons" "Main Page" "Additional 2" through "Additional 5" and "Power". Should I be dropping all my codes from the Transporter??

EDIT: Even when adding new devices for the AVR's MAIN 2 and MAIN 3 IR codes, and assigning those DEVICES the same IR output as the main AVR (port 2), when I drag a code from MAIN 3 to the Macro on the SHIELD page, and the SHIELD device is set to use PORT 4, the code doesn't work. I have to set all devices to use all ports. That's a bummer. I really wish I knew what was going on.
