For JAWS users: When you tab to the tree, JAWS announces that you are entering the tree.
If the tree is a tree table (a table with expandable and collapsible rows) and it has column headers, when you tab to a column header in the tree table, JAWS announces the name of the header and tells you it is a tree column header.
When you tab to a node in the tree, JAWS announces the level of the node, tells you whether it is expanded or collapsed. When you tab again, it tells you the node label. If the node is an end node, no announcement is made regarding whether the node is expanded or collapsed.
When you tab out of the tree, JAWS announces that you are leaving the tree.
