• the computer receiving an input that triggers a shortcut display;
• the computer determining items to display in a shortcut list in response to the received input;
• the computer selecting a display format for the shortcut list;
• the computer establishing an order of the items included in the shortcut list;
• the computer transitioning from a horizontal list view to a shortcut list view wherein the shortcut list is represented as a vertical list or as a grid;
• the computer generating from the shortcut list an updated horizontal parent list with a display item selected from the shortcut list view for display of the selected display item as a current item in the updated horizontal parent list;

• the computer rendering the shortcut list on a display.

A computer readable storage medium, excluding a transitory signal, comprising computer executable instructions that when executed by a processor cause said processor to implement a method comprising:

• managing a plurality of parent lists;
• receiving a request for a shortcut list;
• generating the shortcut list for at least one of the plurality of parent lists;
• and
• transitioning from a horizontal view parent list to the requested shortcut list represented as a vertical list or as a grid in response to the received request, wherein the shortcut list facilitates navigation among item groups of a set of display item groups displayed in the horizontal view parent list by displaying recently selected item groups from the horizontal view parent list upon selection of corresponding display item groups of the short cut list;
• generating a horizontal list view updated with selected items from recent navigation selections, where selected items from the shortcut list are displayed as current items in the horizontal list view;
• and
• providing immediate navigation to a selected display item group from the short cut list.
