Fixing keyboard navigation for MacOS browsers

If you’ve ever used your keyboard to navigate a page in MacOS, you might have noticed you cannot tab through all tabbable elements on the page. Some are fine, such as buttons and input fields, but others (e.g. links) are not reachable using your keyboard.

The worst part is that this is not obvious, and there’s no way for developers to enforce this setting on their sites.

Fixing Firefox

By default, there’s a global system setting to modify this behaviour that you can toggle by going to System Preferences > Keyboard > Shortcuts and then clicking on the All Controls radio button, which is at the bottom of the screen in the Full Keyboard Access section.

Doing this should automatically fix Firefox, which is true to the system settings.

Firefox does not have a separate option for tab key navigation to links and form controls. In Firefox the OS X system preference takes precedence.

Fixing Safari

Safari, on the other hand, has its own setting. By default pressing the Tab key would allow you to highlight all focusable elements on the page except for links.

To change this behaviour, go to Safari > Preferences, click on the Advanced tab and finally click on the Press Tab to highlight each item on a webpage checkbox. By toggling this flag, we can now focus on all elements on the page, including links.

Note that this works for both Safari and Safari Technology Preview and needs to be done separately on both versions of the browser.

Chrome should work fine out of the box

Chrome also has a setting for this under chrome://settings/appearance. This setting is enabled by default, though. So there’s no need to configure anything to make Chrome work.
