Excellent ideas, Felipe. The only one which has already been requested is (a). I'm sure Tyrantmizar will add your vote to that one.
Tyrantmizar, can you also add "b" and "c" to the list? "c" is a "quickie" which I can get done rather quickly. "b" is quick if I make it a separate hotkey, but if I try to integrate it into cntrl-shit-del, it's going to take a little longer.
