Computers are worse at reading your mind than humans. If you can write 
rules that another person could follow, THEN we could help you translate 
the rules to Python.

If you have 1 moderate length file or a few short files, I would edit 
them by hand to remove ignore lines and put a blank line between 
sections. A program to do the rest would then be easy.

This suggests that the rule for keys is 'first 3 words of a line, with 
contractions counted as 2 words'. Correct?

Another possible rule is 'a member of the following list: ...', as you 
gave above but presumably expanded.
