In a lossless undo mechanism history log information on completed actions and reversed actions created by one or more completed undo functions is maintained. The lossless undo mechanism causes an undo loop between a first state created by an action to which the undo function is performed and a second state created by the last reversed action of the completed undo function. The first and second state form a pair of ends of the undo loop. The pairs of ends are used to determine intersecting undo loops. Further, a predetermined rule set is used to determine which one of two or more intersecting undo loops is selected to be outputted as an undo loop in a tree-view structure that is outputted to illustrate the history log information.
