A computer-implemented technique can include establishing, between a computing device and a mobile computing device, a short-range wireless communication link. In response to establishing the communication link, the computing device can provide a selectable option for a user to attach a media item to an electronic document accessed by the computing device. In response to a user selection of the selectable option, the computing device can transmit, to the mobile computing device via the communication link, a command, wherein receipt of the command causes the mobile computing device to initiate a media capture mode. The computing device can then receive, from the mobile computing device via the communication link, the captured media item and, in response to receiving the captured media item, the computing device can attach the captured media item to the electronic document.
