You may select an item, several or all items and mute or unmute them at once.
To select all the items in the course, click on the checkbox at the very top left of Adjust-All HQ and then click on the gear icon and select mute or unmute.
To mute or unmute just one item from Adjust-All HQ, you can also click on the gear icon to the far right of a row and select mute or unmute.
The operation is completed and saved, without your needing to click on Save.
You will receive the standard Canvas confirmation dialog, reminding you what the mute function means for students.
The muted icon will be displayed on the left of the item to help you remember that you’ve muted it.
