Smart actions in the online editor -- where are they?

I am looking at this text in the documentation:

https://docs.rws.com/en-US/trados-studio-cloud-capabilities-812699/using-smart-actions-995155

Where do I find the options described, such as Add term and Insert Tag?

The text also states that "You can bring up the smart action menu at any time by selecting Ctrl + Comma." When I select Ctrl + Comma, nothing happens, regardless of where my cursor is placed.
