Abstract
In a system and method for recalling a state in an application, a processor may store in a memory data representing a first set of previously executed commands, the first set representing a current application state, and, for recalling a previously extant application state different than the current application state, the processor may modify the data to represent a second set of commands and may execute in sequence the second set of commands.
