I don't understand. I typically activate Dom3 by clicking on it. I found a "Dom3config" file, but if I open with a text editor its just gibberish.

how do I activate Dom3 with the -dd switch?
Note: I'm on a Mac, which I know very little about. If I were on my PC, would I open it from a command line? I'm not sure how to do that on a Mac.
