How to detect pressed keys on the click of AngularJS

Question

I\'m using angularjs on a web application that I need to figure out how can I detect is keys like ctrl, shift or alt are pressed when I click so

Answer 1

Since I'm not sure what each browser provides, I would do it this way:

shiftPressed = event.shiftKey || (event.keyCode === 16);

On Chorme for example I can't see any event.keyCode on the click event:

altKey: false
bubbles: true
button: 0
buttons: 0
