This code will fire an alert if I hit either Ctrl key:

$('#text').bind('keypress', function(e) {
    if(e.keyCode==17)
    {
        alert("Boo ya");
    }
});

Any way to only fire the alert if only the left Ctrl key is pressed?

I'm aware this question is quite old but nowadays it seems to be possible KeyboardEvent.code:

document.getElementById('i').addEventListener("keyup", function(e) {
  e.target.value = e.code;
});

<input id="i" value="try keyboard here">

You should get ShiftLeft or ShiftRight by pressing either Shift key.

You can't, at least using the keyCode. It'll be 17 for both keys. I don't know of any other method to distinguish between the two, and in my opinion, it's unlikely that there is one.
