Clicking on the "Click here for help" link at the top of every page will give you an overview of the page, as well as the entire index of help. (If you do not see the entire index, click "show index") From the main help index, you can view all the different help topics, as well as search by keywords and look for definitions within the glossary.
Finally, there are help links next to certain items indicated with question marks. These links provide additional explanation or definitions of specific terms.
