Chuck,
I was not asking for anything from the developer, just some simple
examples of how you, a user, put a couple of pieces together since
you are apparently already using it successfully. I gotta admit I
find it a tad strange that in one post you refer to leap frogging and
the next you apparently want to say RTFM followed by another
admitting that the manual doesn't have all it needs to and shouldn't
at this stage.
