Abstract: In one embodiment, a method includes detecting a change in context of a computing system to a current context, changing a first registration status of a first set of actions with an assistant system associated with the computing system based on the change in context to the current context, where the first application is in a foreground of a user interface of the computing system, changing a second registration status of a second set of actions with the assistant system based on the change in context to the current context, where the second application is in a background of the user interface of the computing system, updating a list of registered actions for the assistant system based on the changed first and second registration statuses, and storing the updated list of registered actions on the computing system.

Abstract: Techniques for page-based navigation for a dual display device are described. In one or more implementations, a journal application maintains multiple different journals. A navigation manager enables navigation through different journals in response to a first set of user gestures, and enables navigation through a sequence of interactive pages of a selected journal in response to a second set of gestures. In one or more implementations, the navigation manager enables navigation forward and backward through the sequence of interactive pages of the journal application using single-page navigation for a dual-display device.
