Abstract: A computing device is described which has a media content viewer configured to render content comprising an image or a video at a display associated with the computing device. The computing device has a processor configured to operate in at least an ink control mode and an ink authoring mode. In the ink control mode at least one ink control element is rendered over a display of the content, the ink control element being selectable by a user to change settings for electronic inking over the content. In the ink authoring mode user input generates electronic ink over the content. An ink mode controller is configured to monitor for and detect specified conditions, and when the specified conditions are detected, to trigger transitioning of the processor between the ink control mode and the ink authoring mode.
