I was able to get the process running - I just open the document, and press a function key and then it does it's magic - saves/closes the document, too.
Basically my day job is an educational technologist - so lots of ripping apart of PowerPoint files (extracting the audio, images and text) which are then re-built for more mobile-friendly formats. Hands-on audio editing, too, and tidying up transcripts (lots of repetitive tasks!) among others.
As far as @martin's suggestion about Python... that might be a longer term project. I currently work full time and study part-time (doctorate in education)... though that said, Python might be good later for (maybe?) research!
I honestly wish I'd looked into KM earlier as I'm already saving a lot of time!
