How to trigger backspace on a textfield?

Say I have this:

<textarea id="myarea">Hello</textarea>

How would i trigger backspace on that textarea possibly using trigger() and key codes. The code for backspace is 8. And i am not looking for this:

$('#myarea').val( $("myarea").val().slice(0,-1) );

I need to simulate someone actually pressing the 'backspace' key on their keyboard. Thanks
