Opera preventDefault() on keydown event

Question

I\'m trying to embed some keybindings in my webapp, and I\'m having hard times with Opera. I have this code:

window.onkeydown = function(e){
  var key = e.ke

Opera doesn't support preventDefault on keydown, only on keypress.

As you can see in this example, you should bind a separate keypress handler for Opera (adapted to your situation):

var cancelKeypress = false;

document.onkeydown = function(evt) {
    evt = evt || window.event;
    cancelKeypress = (evt.ctrlKey && evt.keyCode == 84);
    if (cancelKeypress) {
        return false;
    }
};

/* For Opera */
document.onkeypress = function(evt) {
    if (cancelKeypress) {
        return false;
    }
};
