I'm a newbie. I'm trying to send discrete on/off commands from my MX-850 to my old TEAC receiver. I've got what I hope are the correct hex codes saved in a text file. My next step, as I understand it, is to cut-and-paste these hex codes into ProntoEdit, create a .CCF file, and imoprt it into my MX-850 editor.

I've downloaded ProntoEdit4 and installed it. When I launch this software I'm lost. How do I cut-and-paste the hex codes?

I've looked for a FAQ or other documentation, but thought I'd ask here before I went any further. Any help you could give me, such as pointing me in the right direction, would be appreciated.
