Abstract
Methods and apparatus can scroll a displayed hierarchical data structure. A hierarchical data structure can include a first parent node and a plurality of child nodes of the parent node, the plurality of subordinate nodes including a first child node and a second child node. The first parent node can be displayed in a first position of a display area. The first child node can be displayed in a second position of the display area, the second position being adjacent the first position. The second child node can be displayed in the display area. A first instruction to scroll at least the second child node in a direction toward the first position can be received, and the second child node can be displayed in the second position.
