Summary: Though I would like to see some refinements, this looks really useful as is and I would like it applied soon even if refinements have to wait for a second patch.Moving the window did not generate a printed event.I like the compact way of handling customization.  Two more possible exclusions: 1. The key state seems like it should only be interesting for key events.  2. The 4 mouse positions are pretty noisy and seem not relevant to key events, and to many other non-mouse events.I wish "VirtualEvent event"s had the triggering sequence available, but you cannot change that..
