You can erase digital ink from the interactive screen. However, you're unable to erase some types of objects, including typed text, shapes, straight lines and arcs and imported graphics. To remove these types of objects from a page, you must delete them.
NOTES
You can remove all objects on a page by clearing the page.
You're unable to delete locked objects. To delete a locked object from a page, you must unlock it.
Press the object's menu arrow, and then select Delete.
