* background: I believe I have seen a demonstration of on-screen-keyboard behavior where choices were organized into a menu tree of at least two levels. The submenus were displayed as rows in a grid and the upper level choices represented by the rows. The process of "tool animates focus, user selects one when it is focused" was repeated first selecting rows and then individual choices in a row. This kind of hierarchical descent selection is re-affirmed as helpful in Colvin and Lysley, "Designing and using efficient interfaces for switch accessibility" <http://tinyurl.com/18r> .. but they are talking about designers consciously designing for switch usability, not AT groping their way through the level of structure that you find in the wild on the Web. My question has to do with actual practice applied to general Web pages. * question: My question is: is there any current practice where an on-screen keyboard or other switch-user Assistive Technology uses the nesting hierarchy of a Web page (elements inside other elements) to construct such a hierarchical menu? In which the user gets to choose among the interactive items in the page by page-region group first, and eventually winds up with a group of individual actions that they can activate or not as the scanning passes by?
