There are three really great threads going on at the AskDifferent StackExchange site:
- Terminal Tips and Tricks where people are listing out a ton of terminal tricks for Mac users. Even if you don’t know anything about the Terminal, I bet you can find some neat stuff here.
- Mac OS X Hidden Features and Tricks is another great thread where people are sharing little things about OS X that you may not have discovered yet.
- My personal favoritue os the Mac OS X Keyboard Shortcut thread — I am sucker for more keyboard shortcuts.
