Abstract: A graphical user interface includes a collection of selectable content items, and a command surface for selectively displaying command selectors relating to the collection of selectable content items. Responsive to user selection of a first content item from the collection, the command surface is updated to include a first set of one or more command selectors applicable to the first content item. Responsive to user selection of a second content item, the command surface is updated to include a second set of one or more command selectors applicable to both the first content item and the second content item. Each command selector in the second set is selectable to execute a contextually applicable command related to both the first content item and the second content item.
