Don’t override browser keyboard shortcuts on OS X

[roryokane]

In Firefox 28 on OS X, the demo page swallows most keyboard shortcuts I try to use to control the browser. Any shortcut using a key that the demo uses is overridden, and interpreted as a command to the demo instead of to the browser, as if I had not held down Command. The most annoying overrides are ⌘L to focus the location bar and ⇧⌘{ and ⇧⌘} to switch tabs.

Where the code sets up keyboard shortcuts (probably keys.js or attachListeners in view.js), the state of the Command key should be checked when a keypress is detected. If Command is being held and the shortcut doesn’t require it, then the handler should not trap the keypress event.

Ah yes, sorry about that. I'm devving on a linux box so "alt" is what the keyboard mapping states. I'll have to look into sniffing for Mac
