 ## Overview
 **Spatial navigation (aka Snav)** is the ability to navigate between focusable elements based on their position within a structured document. Spatial navigation is often called the directional navigation which enables four directional navigation. Users are usually familiar with the 2-way navigation using tab key for the forward direction and shift+tab key for the backward direction, but not familiar with the 4-way navigation using arrow keys.
