In :MacPerl Ä:ext:Mac:Menus:t: there is a nice example.

OK.  Set an event handler for your window:

  $win->sethook('key', \&handle_keys);

Then your handle_keys sub:

  sub handle_keys {
    my($my, $v) = @_;
    my($mod) = $Mac::Events::CurrentEvent->modifiers();
    if ($v == 119 && ($mod & cmdKey()) eq cmdKey()) {
      $my->dispose();
    }
  }

Now, I suck at bitmask stuff (darn liberal arts education), so someone
PLEASE tell me if I got the ($mod & cmdKey()) part right or wrong.  But it
seems to work, so what of it?  :)

Anyway, this checks if cmd-w is pressed, at the moment that "w" is actually
pressed.  If it is, it closes the window.
