There is no key code for $, since it's not a valid key - it has to be accessed via some kind of shifter.

Usually, you would perform a check to see if the shifter was active, and the listen out for the keypress event on the relevant key. Something like this for a QWERTY layout in your instance:

var shiftPressed = false;

$(window).keydown(function(e) {  
    if(e.which == 16) { shiftPressed = true; }
    if(e.which == 52 && shiftPressed) 
    {  
        // Do whatever here...
    }
});

$(window).keyup(function(e) {  
    if(e.which == 16) { shiftPressed = false; }
});
