Tabs with Automatic Activation
A Tab will be automatically activated and its associated Tabpanel will be displayed when the Tab receives focus. This implementation assumes the first Tab and associated Tabpanel is always initially activated.
Press Tab and Shift+Tab to navigate focus between the Tab and its associated Tabpanel. Press Left and Right arrows to navigate focus between the Tabs.
On MacOs, press CMD + F5 to enable VoiceOver and try it for yourself.
