2.5.1.2-3 Short Navigational Distances in Hierarchies

Navigation distances should be kept short.

Additional Information:
The interface should be designed to shorten although not necessarily minimize navigation distance. The main menu button is an example of a way to shorten the distance to the top of the menu. Offering direct access to display pages via entry of keywords may impose high cognitive demands when navigating large display networks. It may be more favorable as a supplemental navigation tool for experienced users for frequently accessed displays.
