javascript - Programmatically triggering Ctrl+S

Question

I would like to emit a CtrlS keydown event using JavaScript. Ideally the solution works in most modern browsers (up to IE 9).

I am writing tests and need to test my handler for key bindings. CtrlS is just an example, it can be any key binding with a modifier key. I know about the keyEvent.initKeyboardEvent() method but I was not able to use it correctly to trigger the same event I got when printing out the full keyboard event after pressing the key from the keyboard.

You mean, in order to trigger the browser's "Save as" dialog or something? That's not possible for security reasons. It would be a huge security problem if it were - imagine: every web site could arbitrarily trigger browser functions.
