Via Stefan and John, Tom Yager:

When I use my PowerBook in dark spaces like conference sessions, I find that even the dimmest backlight setting is too bright. Control-Option-Command-8 switches the display to greyscale, then inverts it (in other words, black text on white becomes white text on black). The light output falls by half or more. It looks strange--the Dock icons are a really a trip in negative grayscale--but the entire GUI is perfectly usable. Repeating the hotkey sequence flips back to positive and restores the color.

Now picture me sitting in my car, checking mail via a hospitable WLAN. :-)


Wow! I had never tried that. Works on my old G3 desktop also. Excellent.
