Hover boxes allow the user to hover over bolded text and see a definition for that text. If the bolded text is blue, there is a link to more information.
We have only begun to use them since June, 2019. When we modify older pages, we will incorporate hover boxes into updates.
This page lists standard definitions used in hover boxes throughout this manual. Hover your mouse over any bolded term and a definition will be displayed. This list will continue to expand as new terms are encountered. You'll note that some terms have not yet been defined (not bolded).
