I use Mac OS X (10.7.5)
I wonder how I can turn off screen only of my MacBook without closing the lid, without waiting for the screensaver. The best way I can currently do is just to close the lid or to repeat 'F1' key to dim it.
Is there any shortcut key to do so? I use this frequently when I read a book or a paper with the laptop turned on (not sleeping) to avoid distraction.
