You missed the part where I say I have it work in muO... I just test for 
controlKeyPressed in mouseMove and that's it. But I first need to 
inhinbit the meta menu, and this is what my suggested patch allows.

So, I do not see this as a side-effect to tryInvokeMetaMenu, but simply 
as a hook allowing me to bypass the meta menu mechanism. I really don't 
mind if you put that hook anywhere else, but it is useful, because it 
allows a drag gesture to happen while CTRL is down. That's enough for 
me, and that's enough to have CTRL+DRAG gestures by testing for 
controlKeyPressed in mouseDown events.

If you want to see it in action I can send you an example image.

Best,
