Abstract: A method, data processing system and computer program product for maintaining/updating managing keyboard navigation using a linked list. In particular, a Dynamic Tree Control Linkage (DTCL) utility creates a doubly linked list with list nodes having assigned values based on a tree control structure UI component. Each list node of the doubly linked list corresponds to a visible tree item of the tree structure UI component. Responding to a keyboard event signal, the DTCL utility finds a current list node corresponding to a first current tree item. The DTCL utility finds a next (i.e. previous or subsequent) list node corresponding to a next tree item. The DTCL utility detects a list node exists. The DTCL utility detects whether the next list node is associated with a null value. When the next list node is associated with a non-null value, the next tree item is identified. The DTCL utility returns an identification of the next tree item representing a second current tree item.

Abstract: System, computer implemented method and computer program product for dynamically updating a Web page using browser-based messaging. A system for dynamically updating a Web page using browser-based messaging includes a Web page that includes a plurality of Web messaging tags, and a selected data model that can be bound to the Web messaging tags, and at least one messaging client for accepting at least one message from a message server and for processing the accepted at least one message into the selected data model.

Abstract: Accessible role and state information may be included in hypertext markup language documents by encoding an accessibility definition into a class attribute. The accessibility definition corresponds with an object of a hypertext markup language document and comprises role information and state information if state information is applicable to the corresponding role information. A script is associated with the hypertext markup language document and is configured for parsing at least a portion of the hypertext markup language document to identify the accessibility definition. The script further maps the role information and the state information in the accessibility definition to corresponding namespaced role and state attributes.
