second user may often interrupt what the first user is doing. Alternatively, the first user could zoom out of her or his section and manually search, in an unguided manner, the shared data for the section being worked on by the second user. Such efforts are inefficient with respect to the consumption of time and/or computing resources. [0004] The techniques disclosed herein provide a computationally efficient human- computer interface for collaborative viewing and/or editing of content. Among other technical benefits, the techniques disclosed herein can reduce utilization of computing resources by simplifying the collaborative process for viewing and/or editing content in a multi-user collaborative workspace. As described herein, data can be shared amongst a number of users, each utilizing separate devices. Thus, the data may be referred to herein as a “shared” data (e.g., a data unit such as a file). Further, individual users may separately edit (e.g., create, modify, etc.) content in a particular section (e.g., area, region, page, etc.) of the shared data. A result of this separate editing may cause sections of the shared data to be off-screen from a perspective of a user and/or a computing device being used by the user. [0005] The disclosed techniques provide an efficient and 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. For example, one user may want to collaborate with another user about the content. In another example, one user may want to ask another user a question while both are simultaneously viewing the content. In yet another example, one user may want to let another user know they have completed an assigned group task and her or his completed work is ready for review (e.g., a second set of eyes). [0006] As described herein, a request for a user to view content may be referred to as a call for attention to a section of shared data. Calling attention to a particular section of the shared data can be implemented in a graphical manner. For example, a user interface element can be displayed on a display screen being viewed by a user that has been requested to provide attention to a particular section being edited by another user. The user interface element can be displayed in a non-invasive way that does not interrupt the work being performed by the user. Moreover, the user interface element can continue to be displayed, over a period time, in order to make sure the user is aware that the other user has requested her or his attention. In various examples, the user interface element is selectable, and thus, the user interface element provides a mechanism for the user to efficiently switch a display screen to content which the user has been requested to view. This can be implemented at a SUMMARY
