Triple shift pops up a red "Access Denied" message in the middle of the screen. Alt just shifts focus to the browser's toolbar, at least in Chrome.

Alt alt alt should show a big green Access Granted :)

It just opens/closes the file/edit/view menu.

If you press it enough times, eventually three alt keys will get through to the page and it will pop up. I think it could could prevent the menu appearing by using preventDefault() on the keydown event.

> Come on... come on...

Suddenly, the screen flashes red: "ACCESS DENIED."

> Dammit, they're trying to lock me out.

Fingers fly across the keyboard. Sweat drips from their forehead.

> Not today, FBI...

The warning turns from red to green: "ACCESS GRANTED"

> I'm in.

> Let’s see what you’ve been hiding...
