Aha! Thank you. All right, this completely makes sense. What about when Emacs 
doesn't connect to X Server? Cocoa, pgkt, etc. Or is it vital to keep the model 
for backward compatibility and consistency?

I can't be the first person asking this question: "why can't I bind a command 
to a key-release event?", right?
