- Focus is trapped within the modal and users can then navigate through the dialog actions with the keyboard.
- Escape will close the modal. To disable exiting when users press the Escape key, set the
escapeExits
prop tofalse
- When the modal closes, focus returns to the element that was focused just before the modal is activated
