While browsing through the comments on this 43 Folders post about a bare-bones no-distractions text editor, I discovered a keyboard shortcut in Mac OS X that inverts all of the colors on your screen! Just hit control-option-command-8. Mostly white screens really suck in dark rooms, so I’m digging the ability to turn everything mostly black at night. And having everything look like a photographic negative is pretty awesome as well 🙂 Unfortunately, taking a screenshot doesn’t capture the effect, although I suppose I could just take a normal screenshot and invert the colors in a graphics editor so that you could see it 🙂
Apparently there’s a similar shortcut for Windows XP, “left-shift, left-alt, print screen”, which allows you to switch into a high-contrast mode (also accessible and configurable via the control panel)? I wouldn’t know, I don’t have Windows XP, but if you do you could try that.
