this link to starshipchangeling for instance. it says "g" and "N" to go to Notifications tab. I don't use JAWS on here, because the keyboard is braille layout to make it small... but it's not specifically for blind people; so it looks like a totally normal keyboard, in no specific Accessibility mode turned on. it's in Braille to make this mechanical keyboard with chonky keys fit in my pocket.

ie: I am betting that a lot of people would learn a chorded keyboard layout if the keyboard is on the back of an iPhone case; and braille is amazing for that task. but the keyboard appears US qwerty to the OS.
