Move, copy, delete, or update the visibility of multiple items at one time with Bulk actions!

Apply bulk actions to items. 

Select the targeted items. Open the Bulk actions link at the top of your course page and select the desired action from the options  at the bottom of the page. Keep in mind that any section that you delete will remove all of its contents at the same time. (And if you get carried away, remember that deleted items can be restored from the recycle bin!)
