The Tabbing component removes, only for non-tabbing users, the ":focus" outlines. It hides the default blue browser outline for everyone, except for the users that have hit the tab key. This component waits and listens when the user presses the button that all keyboard navigators will press to inform you they're planning to use the keyboard. And when the user presses the Tab key, this global component adds a class to the body that adds ":focus" styling.
