Notes

Mac OS X "Full Keyboard Access" refers to setting Keyboard→Shortcuts→Full Keyboard Access to "All controls" in the System Preferences.

"Unknown" support for mobile browsers is due to lacking a method of tabbing through fields.

  1. On Mac OS X, unless Full Keyboard Access is enabled, <a> elements are not keyboard-focusable, even if they have tabindex="0".

  2. <a> elements are never keyboard-focusable, even if they have tabindex="0". Unless Full Keyboard Access is enabled, then <button>s, radio buttons, and checkboxes are also not keyboard-focusable, even if they have tabindex="0".

  3. Has "previous" and "next" virtual keyboard buttons that follow tabindex order.
