In the Author environment, click on the Glossary tab.
Next, click on the new button in the top left.
You will now see a screen with three fields:
Name: Give your new theory page a name
Status: Do you want to publish your glossary already? Publishing it means it can be attached to theory pages and exercises. Is it just a draft? You can leave it unpublished, but remember to publish it when you're ready!
Author group: Choose within which author group you want to create this glossary
You will now see your newly created glossary in the glossary list. Click on the A icon to start adding words and definitions. You can do so by clicking on the Create word button on the next screen.
You will now see five input fields:
Author group: Choose within which author group you want to create this definition
Word: What word do you want a definition for?
Description: What definition do you want to show when students hover over the word you selected above?
Keyword(s): You can add keywords to help you organise your glossary.
Alias(es): You can add multiple words for which the same description will show.
When you're done, click on the Save button to save your description.
