Calendar - day/wee view- Handle single click outside event

Hello,
1/ Is it possible to catch users click inside caledar grid outside event (I need to open window with default time, if user clicked just once). Is it in roadmap?
2/ is it possible to detect if user pressed ctr/shift with click?
3/ is it possible to detect double click?

I’m using vaadin 7.1
Thank you
