Blackboard 9 uses a Modify button beside any item you can edit or whose behaviour you can change. You will be used to seeing the Modify, Manage, Copy, and Remove buttons beside content in Blackboard 8. In Blackboard 9 there is just one button, the modify button. This brings up a menu showing all the actions you can do with an item.
