Keith,
Thanks for the info on X-10 dim/bright commands and the insite you have on learned codes.
In fact, in the software, you cannot "disect" IR codes specifically but you are able to move/copy commands around under buttons and add pauses as required. In case this is not clear, what I mean is any button can encompass a "macro" or string of commands.
You might just have the actual buttons in a separate CCF file, and when needed, merge it in, take the bits you need for the actual buttons you want, then purge it back out of the loadable file.
