Hi All,

I have been doing a bunch with regex's lately.
I just throw them out based on prior experience
and they most all work now.  I only sometimes have to
ask for help.  (The look forward () feature
is sweet.)

Anyway, I have been using regex switches without
knowing why. So

What is the difference between

\N
:\N
<:\N>
<<\:N>>

And why would I choose one over the other (what
are they called out for)?

Many thanks,
-T
