I'm not sure why you're being told that this is impossible?

The delete key is 46, so this should work:

$('html').keyup(function(e){
    if(e.keyCode == 46){
        //delete key has been pressed.
    }
})

Also note: You should be using either the keyup or keydown event rather than keypress. keypress is intended for real character. 'keyup'/'keydown' is handled at a lower level so it will capture all non-printing keys like DEL and ENTER.

You're missing a `;`. Use `which` (it's shorter!) (Kidding) – Roko C. Buljan May 29 '13 at 11:48

Thanks @RokoC.Buljan I'm aware of the limitations with minification. In this instance it would make no difference. For reference: many JS compilers/minifiers will strip unnecessary semi-colons, including the YUI Compressor. – johnkavanagh May 29 '13 at 11:52

jQuery will handle `which` like all other charcode keycode guys. – Roko C. Buljan May 29 '13 at 11:47
