The fastest way to rename a lesson category, question category, or flashcard category is to visit the relevant page in the Structure section.
Click on the category’s name you wish to change. A textbox will appear.
Type in the new category name, and hit Save underneath the textbox.
NOTE: This save won’t save the category name — it allows you preview the name in the list.
To commit the category change, you will need to additionally press the Save button at the bottom of the Categories page.
Additionally, you can press the Pencil icon to edit an appropriate category. You can rename the category in this window and press Save.
