cool mac trick

If you own a Mac, there is a cool feature that I use quite often. I don't know what it's called but what it does is inverts all the colors on your screen - creates a negative image. I use it mostly in the early morning when my eyes are still adjusting or when I'm in a very sunny situation and I have a hard time reading a white screen. Here's how you activate and deactivate it.

Hold down "Control, Option (Alt), and Apple (command)" and hit the number "8". Do the same thing to deactivate the feature. I've never tried it on a PC, let me know if it does.

I tried taking a screen shot with the feature activated so you could see it but screen shots bypass the feature so it didn't work.
