Just for fun I tried programming macros on the device keys using JP1. I started out with the "My System" key to program a macro to start up and configure my entire system. And it worked fine. Then I tried all the other device keys. They also allow you to program macros on them. I am using the shifted device keys but I also tried the non-shifted and they work great. I thought that the 15-1994 needed an extender to acomplish this but never followed up since the 1994 had 1s-4s.

To the real experts,
Can I keymove a device key to the shifted device key and then install a macro on that same device key. (example: copy DVD to Shift-DVD and then put a macro on DVD to power up the DVD and config the system.)

Mr Bill,
I don't know what you mean by activating instead of programming but if you are asking wheather you can program any device keys without JP1 the answer is no. The onscreen menu will not let you program those keys.
