There are number of shortcuts, tips, wallpapers, etc, documented on the askubuntu thread below. It's a good start that will likely have the information you're looking for.

Hi All,I particularly like Ubuntu's keyboard short-cuts. Most (if not all) of my friends at the Tyneside LUG are unaware of them. I was thinking of writing a mini-article about them for the ACCU's CVu magazine and I was wondering if there is a page out there that lists them? I know if you hold the "super/Windows" key, you get a list of some of the short-cuts and was wondering if they were also listed on a web page.Thanks :)Ian---- ACCU - Professionalism in programming - http://www.accu.org-- My writing - https://sites.google.com/site/
