The **cypress-plugin-tab** adds a `.tab()` command to Cypress that lets developers programmatically simulate pressing the Tab (or Shift‑Tab) key to navigate focusable elements within their tests. It's aimed at Cypress users who want to write integration or end‑to‑end tests that need to mimic keyboard navigation and focus changes, especially when testing forms, focus management, or accessibility features. The plugin is currently in beta and distributed via npm.
