Mac OS Tips& Tricks
- Hold "command" + "option" + "control" and hit the "8" key to inverse the screen colors.
- Photo Booth: Hold the "option" key to skip countdown and take immediate photo. Hold the "shift" key to disable the screen flash.
- Hold down the "shift" key during almost any OS X animation to watch it in slow motion.
- Hold option + shift while adjusting the volume with the volume keys on the keyboard to adjust it in more granular increments, hold just option "down" to bring up the sound system preferences panel
This doesn't actually count as a Mac trick, but is still a pretty cool trick nevertheless.

Here's a neat easter egg trick to get a Snake Game in Terminal.
Open "Terminal" within Applications >> Utilities.
Type in "emacs", then press enter.
Within emacs hold down ESC and press X.
If the cursor is on the bottom of the terminal, type "snake".

This isn't really a part of the Mac OS, it's a part of emacs which is part of the UNIX system. Most Mac users don't know this is included with their computer. There are many more games included as well. To know what other games are included, do the following:
Open the terminal again, at the prompt type:
"cd /usr/share/emacs/"
"ls"
read the VERSION NUMBER of emacs then put this in the command below
"ls /usr/share/emacs/VERSION NUMBER/lisp/play"
In my Mac the VERSION NUMBER is 22.1 so I need type
"ls /usr/share/emacs/22.1/lisp/play"
Don't forget the space in after "ls"!
You'll get a directory of the games included with emacs,
to play these games do the same thing as with "snake",
except type your chosen game's name in place of "snake".


- Finder: When drag & dropping files across volumes, hold down the "Command" key to move the file instead of copying it.
