Control and Alt are special in that they aren't expected to switch levels, and so don't need to change what characters are output. Use in layouts by adding `modifier: Control` or `modifier: Alt` in place of `text: "foo"`. The latching of the modifier will force the keyboard to emit raw key presses and prevent it from outputting text.
