What key does this ⇥ symbol represent in Apple help docs? Please help figuring out what this ⇥ key modifier refers to, in Apple's instructions in iPhone 6s settings below as shown in Settings app → Accessibility → Keyboards → Full Keyboard Access.

E.g., What key combo do I press on Apple bluetooth keyboard to invoke Notification Centre? I've tried Control + N, Option + N, Command + N, Fn+ N but to no avail. The keyboard is properly paired with the iPhone, and I can type text or navigate with the arrow keys.
⇥ symbol refers to the Tab key on the keyboard.
