This allows the ability to mark an action as repeatable, which when set, makes it so that it will change only the redo value for the last undo item in the undo stack within the last three seconds. This allows the ability to, for example, scroll a spinbox or change a slider value without creating many unnecessarily duplicated undo/redo actions.
