You may have spotted a 'Deep Links' menu item under the Administration section of the Navigator menu. This opens the page below, showing a collection of pages. These are pages within Core HCM product family who are the first to adopt a new deeplink framework.
The existing deeplink mechanisms (discussed here) remain, therefore just leverage the capability that is available for the pages you wish to link to.

The 'Deep Links' page (screenshot above) is simply a listing of pages for reference, and it is not possible to create new registrations or change page registrations at this time. If you find pages which cannot be linked-to, using this or the existing deeplink methods, please log this enhancement requirement for Oracle Support to get the page registered in this new framework.
