Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I take it that your lines start with a lowercase letter
followed by a '.' (dot) followed by an opening parenthesis '('
then a lowercase letter followed by a comma ',' and a lowercase letter
in which case this should work in vi:
It looks for strings that start with a single letter
followed by '.' then 'junk(' then a letter, then ','
then a letter
if the next character is ')' it inserts ',' then 'YAHOO'
before the closing ')'
I was trying to simplify the problem with the example I stated. Unfortunately your solution does not help in my actual case which is much more complicated.
All i am looking for is "exception of a word". I want to exclude lines where some known words (or collection of chars) appear. The sed example of grouping with // and then negation !s was perfect. I dont know whether sed will take other parts of my regular expression such as back referencing with \1 etc. I am trying to avoid reading tutorials on sed so its equivalent in vim will be useful.
