I will give plenty of karma to anyone who can tell me an easy way of doing something even remotely similar in Linux. I'd love it.

On Ubuntu the first thing I do with a new install is rebind quit to Command W. (System -> preferences -> keyboard shortcuts.)

If you're using Firefox you just make sure browser.warnOnQuit is set to True (out of the box, it's set to true.)

As far as Chromium goes, near as I can tell ctrl-Q does not work at all, which is something Firefox would do well to imitate.

Chromium uses Shift+Ctrl+Q to exit.
