Does anyone know if there's a way to sleep only the screen with a keyboard shortcut or something like that? i know i can set the screen to sleep in the system preferences, but i'm asking if there's a way to make it happen when i want, like how you can set a hotcorner to start a screen saver.
A related question: is it okay to sleep and wake my ibook throughout the day, say 10 times a day? i figured it might be better to just sleep the screen (screen savers still use backlight), hence the above question.
thanks,
robert
