Force-Sleep the Display on a 2010-2011 MacBook Air

[Update: It looks like Mountain Lion finally restored this functionality—you can press Shift + Control + Power key, and the screen will immediately go to sleep.]

The 2010/2011 MacBook Air models are all amazing, and I believe Apple will eventually convert all their Mac laptops to the same basic design (just different sizes), forgoing the optical drives.

The only downside to this new design is the lack of an eject key—of course, most people probably only knew the key could eject discs, so it's no big loss for them. I, however, use that key in a standard Shift + Control + Eject combination to instantly turn off my Mac's display to conserve power and prevent any pixel ghosting. I've used the combo for a few years, and it took me some time to find out a way to reliably do something similar on my new 11" MacBook Air.

There are a few ways you can get this functionality back:

Dreaming in Drupal

How do you know you've been thinking about work too much? When your wife relates a conversation she had with you in the morning, and you don't remember a word, but can definitely see how what you said relates to what you're working on:

Saith my wife: "Jeff, how do you set your alarm?"

My (groggy) reply: "Hit field, the arrow, then default."

Now, this could possibly have something to do with alarm clocks. There are often arrows on them, and you hit buttons... but I know better. I was referring to:

$this->addFieldMapping('field', 'source')->defaultValue(0);

...which I have probably typed about 100 times in the past week, and maybe 20 or so last night during a late-night debugging session with the Migration process of flockNote v2 to v3 (from a proprietary WAMP-based system to a new Drupal 7 LAMP-based system).
