.N to the left of the = means Not shifted (opposite of .S).

.N to the right of the = means menus Not active (opposite of .U).

Basically, I goofed when added .U/.N, in that I missed the fact that .N was already used..

The 15-second thing I referred to was for the "Countdown Timer Timeout", aka "QuickTimer" (same thing). I didn't read your FAQ enough the first time, so what you have there is mostly correct. But the actual increments for the intervals are even more complex than the FAQ says.. and the whole deal sounds way more complex than the function actually is when used.. might be better to just not talk about the increments at all.
