Abstract

Methods and apparatus, including computer program products, implement techniques for navigating user interface elements of a computer program application. A navigation key press of a navigation key is detected, where the navigation key has a group identifier. A selected group of user interface elements associated with the group identifier is identified. Input focus is shifted to a user interface element in the selected group based on the navigation key.
