Taken from `man xdotool`:

> Type a given keystroke. Examples being "alt+r", "Control_L+J",
> "ctrl+alt+n", "BackSpace".
>
> Generally, any valid X Keysym string will work. Multiple keys are
> separated by '+'. Aliases exist for "alt", "ctrl", "shift",
> "super", and "meta" which all map to Foo_L, such as Alt_L and
> Control_L, etc.
>
> In cases where your keyboard doesn't actually have the key you want
> to type, xdotool will automatically find an unused keycode and use
> that to type the key.
