SlickCursor (download)
SlickCursor is a mouse emulator that performs on-the-fly screen analysis.
You can move the mouse cursor up and down, over navigable screen sections - a functionality that resembles menu item selection, with a single key press.
Navigable sections are detected on-the-fly, while users operate the application. The sections are never displayed on the screen because users don't need to be aware of them. They are visible only through the Inspector window.
