Awesome. Thanks for all the clarifications... mashing all the info together from tons of posts obviously resulted in some mistakes. I made the appropriate changes in the FAQ.

Stuff I'm not clear on:

When you say:
The countdown timer increment is actually variable, rather than a 15-second constant.. best just to not mention the increment.
... are you referring to the Screen Blanker Timeout? 'Cause I can't find anywhere i've mentioned Countdown Timer Timeout as being 15-seconds.

You said there's another .N modifier that works only on the left of the = sign that means "not-shifted".
So the .N modifier means different things depending on which side of the = it's on? Confusin' i says. Could ya change one or the other to a different modifier so it's more obvious? Or should i just define the .N as both.

Thanks again!
