The initials (ppt) after a keyword indicate that it is a Powerpoint presentation and the initials (doc) indicate that it is a Word97 document. Otherwise, the pages are written in html.
There is a certain amount of inconsistency, and you may find that I've rambled a bit in places. This is because I've taken things that I've written in different contexts, and included them here. This list is constantly being updated on a fairly regular basis, but I'd appreciate feedback as to how it could be improved - grammar, spelling, pictures, or words included.
