Abstract: Technologies are disclosed that enable a computing system to provide a computationally efficient interface for collaborative viewing and/or editing of shared content. Individual users may separately edit (e.g., create, modify, etc.) content in a particular section (e.g., area, region, page, etc.) of a shared data unit such as a file. A result of this separate editing may cause sections of the shared data unit to be off-screen from a perspective of a user and/or a computing device being used by the user. The disclosed techniques provide an effective way for an individual user, of a multi-user sharing session, to request that other users view content being edited by the individual user in a section that is “off-screen” for the other users. Based on the request, a selectable user interface element can be displayed enabling efficient access to the content to be viewed by the other users.
