Roger. Thanks, but I was already was aware of that. Sorry I wasn't clear.

I have not been able to figure out how to use that macro window to test and act upon a variable.

In essence what I am attempting to do is to return to an Activity if the user has gone to the Devices (Main2) pages for more device commands.

I want to design a macro for the "PREV CH" key that returns from the Device page back to the Activity page that called it.
