You can add a helper function to return the right modifier per platform and use
it in the test above as well. Here, you'd need to do:

int modifiers = blink::WebInputEvent::ShiftKey | GetPlatformModifierKey();

Done. I made a const variable for the default modifier.

+  int modifiers =
+      blink::WebInputEvent::ControlKey | blink::WebInputEvent::ShiftKey;
