Tabbed interfaces should be keyboard-navigable to meet accessibility requirements. At the moment, the accessibility toolkit page's tabs only can be navigated using the tab character.

The WAI-ARIA Authoring Practices 1.1 document provides guidelines for writing a tabbed interface.

The keyboard interaction for the tabs should be as follows:

• Tab
  • When the focus moves into the tab list, places focus on the active tab element. When the tab list contains the focus, moves focus to the next element in the page tab sequence outside the tablist, which is typically either the first focusable element inside the tab panel or the tab panel itself.
• When the focus is on a tab element in a horizontal tab list:
  • Left Arrow
    • moves focus to the previous tab. If the focus is on the first tab, moves focus to the last tab. Optionally, activates the newly focused tab (See note below).
  • Right Arrow
    • Moves focus to the next tab. If the focus is on the last tab element, moves focus to the first tab. Optionally, activates the newly focused tab (See note below).
• When the focus is on a tab in a tablist with either horizontal or vertical orientation:
  • Space or Enter
    • Activates the tab if it was not activated automatically on focus.
  • Home (Optional)
    • Moves focus to the first tab. Optionally, activates the newly focused tab.
  • End (Optional)
    • Moves focus to the last tab. Optionally, activates the newly focused tab.
