These are not used yet.

drive-by: other native code uses ui::DomCode::ALT_RIGHT as an id, why is this
different?

[nicholss, 2017/05/12 20:45:58]

those are not what I want. I am making a bit mask to send in so I can say send
this key event and wrap it with some modifiers.

+#define SHIFT 0x04
+#define CTRL 0x08
+#define CMD 0x10

Could you use the KeyEvent struct in the protobuf instead of defining a new
type?

[nicholss, 2017/05/12 20:45:57]

Maybe.  the side-effects of the fields in the proto are more than I want to deal
with so, yes I can use it as a shell, but it will not be an honest usage of the
data it might contain.

+  bool keydown;
