Thank you all very much for the nice comments. As you might surmise, I worked very hard on this, and if I helped just ONE person understand this awesome and under-used feature more, then I consider my effort a success.
Glad to hear that people are finding it useful.
By the way, in Cuabse 6.5 you don’t need a macro to activate the listen button on a selected channel. You just need the “Mixer → Channels: Listen On/Off command” (as Bredo reported). This is a primary reason I can’t use Cubase 7 for my main projects yet, as it’s activate listen command does not affect the “selected channel” it effects only the red highlighted channel in th mix console. There’s a difference, and it’s a real pain in the butt. And I agree that Cubase 7’s implementation of the control room is … not as good as Cubase 6.5. 
Anyway, I’m not hear to complain. Just to thank you all for the support. Thanks again.
