Abstract: A facility is described for providing shared telepointers and for enabling hosts and participants to highlight portions of documents or applications using the shared telepointers. In various embodiments, the facility establishes a sharing session wherein an application executing on a host computing device is shared with a participant computing device, receives at the host computing device an indication from a participant computing device to identify a region to users in the sharing session, draws the identified region on a display device associated with the host computing device, and causes the identified region to be drawn on a display device associated with the participant computing device. In various embodiments, the region is a spot region or a highlighted region that is drawn in a color associated with a user of the participant computing device.
