Add modifier keys to jump to assigned vehicles

I know you can click on the vehicle's icons to move the camera to the assigned vehicles, but there is no way to directly open the vehicle's UI.
I would suggest:
Left Click: Open GUI
Shift + Left Click: Move camera to vehicle
Ctrl + Left Click: Follow vehicle

I can't find a way to edit the OP so I'll just comment here:
Just look at how OpenTTD does it and copy that.
