Here are some of handy tricks and tips I've collected.
Here's an applescript I wrote for locking my Mac, I use it daily:
do shell script "/System/Library/CoreServices/Menu\\ Extras/User.menu/Contents/Resources/CGSession -suspend"
Save it as a service using automator, and then set a keyboard shortcut in System Preferences -> Keyboard. I'm using Shift-Command-L.
I find this method far better than the old keychain access trick because it doesn't require an extra icon in your menu bar; it's invisible, and as an added bonus, you get a neat animation. Enjoy!
