On the apple website it says shift + ctrl + eject for making the display go to sleep. But I've tried this and it never works. Making the mac go to sleep works though, I use it all the time; option + +eject. Is there a way to see if the key combination is assigned to another program? I haven't changed it myself so unless it was reassigned when I installed some app. Running OS 10.4.11 on Macbook C2D 2.16GHz cheers, b.
