Cell Navigation

Cell navigation is a method of accessing tabular data non-visually by moving between individual cells using directional commands (up, down, left, right). Rather than reading a table linearly from top-to-bottom, cell navigation allows screen reader users to traverse the two-dimensional structure of a table, maintaining awareness of row and column context. Modern screen readers implement cell navigation through keyboard shortcuts (e.g., Ctrl+Alt+Arrow keys in JAWS), announcing row and column headers as the user moves between cells. This interaction pattern was first developed in the late 1990s to address the fundamental mismatch between the 2D visual layout of tables and the linear output of screen readers.
