Gmail currently has some sort of keyboard icon in the top right, that lets me choose between "English", "English Dvorak", "English" and "English". There's no explanation of what it is or what it does. Since I know what a Dvorak keyboard is, I can guess it's some sort of keyboard settings. I deeply fear switching from "English" to "English" (or perhaps to "English" instead) because it seems likely it will be hard to recover from, so I haven't tested to see what it actually does. Perhaps "English" is the right setting for me instead of "English" or "English". I'll never know.
