Jquery keypress except: {something}

Question

Is there any shortcut( actually a function) in jQuery or Javascript to handle button press except something, or only something, e.g.:

$(input).keypress('nonfunctional' function(){ 
  // do something
});

that will trigger only on [a-z][0-9] buttons pressed and ignoring single shift or ctrl but handling shift+a => A pressed?

P.S.i do know about if(key.code == 123) then ...

Answer 1

No, if you want to exclude specific keys that's what the event.keyCode / event.which properties are there for.
