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 `...`
