"Only waiting for Radio Shack to send me codes"

Good Luck - if Radio Shack has advanced code lists better than those on hifi-remote.com I'd be stunned. Try this link, which is indexed by the UEIC code for your device:
[Link: hifi-remote.com]
If it's not there, a way to find advanced codes is to go to the file section here at Remote Central, and look for a CCF file for your device. Get the CCF2EFC utility, and execute it against your .CCF file. This will tell you the Enhanced Function Codes for each of the buttons that someone has built into the .CCF.
[a CCF is a configuration file for a Philips Pronto Remote, which has been dumped to a PC].
You can also use Setup-x-y-z to sequence through all possible advanced codes for your device (xyz = 000, 001,002,...255). When a code does something, write it down; Share the compiled list with Rob at www.hifi-remote.com so it'll be there in the future.
