I cannot activate the Data Category Groups using my screen reader. There is no key icon next to the group I created to activate it.

Hi Racquel,

The key icon reference comes from older Salesforce Classic documentation. In Lightning Experience, Data Category Groups are activated using the row-level action menu or directly from the group's detail page rather than a standalone key icon. 

1.Navigate to Data Category Groups:Setup. 

From Setup, enter Data Category Groups in the Quick Find box and select it. You can verify success when the list of category groups displays on your screen. 

2.Open the Row Action Menu:Action Menu. 

Locate your category group in the list and use your screen reader or keyboard navigation to reach the action dropdown menu button at the end of the row. You can verify success when the action menu expands to show options like Edit, Activate, and Delete. 

3.Select Activate:Activation. 

Choose Activate from the menu and confirm. You can verify success when the group's status updates to Active in the list view.
