>Dave, is a programming background necessary? How difficult is it to put this to work?

I started to write a long answer to this question, but decided on a shorter one instead...

Q) Is a programming background necessary?
A) To do simple things, probably not. To do more complex things, probably yes.

Q) How difficult is it to put this to work?
A) It depends. Michael already has provided lots of simple one-liner scripts that you can bind to keys. That's pretty easy, and something the docs I'm writing will help you explore. Beyond that there are lots of possibilities, with varying ranges of complexity to implement. I'm still looking at ways to approach this.
