Q: Press power button once - MBP goes to sleep, Shift-Control-Media Eject (⏏) doesn't.

Hello, i've read here http://hints.macworld.com/article.php?story=20131025154203251 and somewhere else, that in Mavericks, pressing the Power Button once, puts your screen to sleep.

But after reading here http://support.apple.com/kb/HT5869 seems that it doesn't.

I also noticed that by pressing it once, your mac goes to sleep, but not immediatly.

So is the only way to put only the screen to sleep is by using Shift-Control-Media Eject (⏏) ?

Thank you
