摘要
An action history maintains a set of ordered application actions associated with a user. A user interface of a software application can include a back control and a forward control, which utilize the action history. Specifically, the back control revokes a most recent action and the forward control reapplies a previously revoked action. Thus, the forward and backward controls change which page is rendered in the software application. Unlike traditional implementations, the invention maintains a complete set of actions within the action history in a non-linear context. That is, when a new action is inserted into a history from a non-terminal state (i.e., actions able to be reapplied are available upon a selection of the forward control) then the new action is inserted immediately after the current action. The historic actions are maintained in order after the new action in the action history.
