JoeS must have misunderstood the UI of ProntoEdit.

Double click one of the RC5 signals (such as the one for a hard Key on the right side of Device Properties).

You get to the Add IR dialog:

It shows Devices = "A Proc", Brands = "Non applicable", and a big list of Functions.

I can see how a beginner might get confused and think that information has something to do with the contents of this device in this CCF file.

In fact it doesn't. It is a gui designed to help you CHANGE the signal to one selected from the database. But it lets you select functions from non existent code sets or select non existent functions from actual code sets (the complete list of database functions is always shown even if some of those functions aren't in the selected code set or even if the selected code set doesn't exist).
