Hi Michael,
I understand what you're saying about the confusion factor. You've obviously done a LOT of thinking about UI issues. That's why I said that the question would be asked only if there were things selected when entering the command. However, that may not be enough to keep things clear.

I understand that you're not particularly interested in tutoring people in programming add-ons to your software. I have had some basic classes in Javascript and C++ (the dreaded C++). I very much appreciate the information that you have already given me. I'm sure it is a difficult task, but others have done it. This will be a background project for me after several other projects that I have going on.

Thanks,
Mark
