The delete action allows you to delete several entries from your application at once. You can use the action in a Table view.
Select the entries you wish to delete by clicking the check box next to each one in a view. (Or, if you wish to delete all entries in the view, leave all the check boxes unchecked.)
Open the Actions… menu, and select Delete all, or if you have checked particular entries, Delete checked.
The entries will be deleted immediately. If you make a mistake, you can use Undo to undelete the entries.
