问题 Is it possible to handle MouseDown/MouseUp and KeyDown/KeyUp evens with Vaadin? I've found forum thread with the same question and looks like the answer is no, but it was 5 years ago - I hope something changed with later releases. Still I can't find anything in API.

Required component has to be wrapped with extension-interceptor (credits to @petey for an
