Using the Glossary
As you explore the site, you will see entries marked like a link with a little book in front of the first word. If you hover your cursor over any such term, you will be presented with an extraxt of the term, and if you click the link or the “Learn More” you’ll get the full definition. Hit the browser’s back button to go back if you go to the Glossary for the full term.
And you can get rid of the pop-up tooltip displays by either clicking their “Close” buttons, or clicking outside of the extract, or just ignore them and they’ll go away after a second or two.
