A simple time saving tip that I’ve found useful is to quit open Applications without switching to them first. I’ve got two time saving ways to accomplish that task, first through Mac OS X’s built in Application switcher (Command + Tab) and secondly the Mac OS X Dock.

The Application switcher built into OS X and accessible through Command + Tab, this allows you to quickly switch between open Applications. By striking Command + Tab once and holding down the Command key you’ll see something like the screenshot above with icons for each running Application on your Mac. Pressing Tab again will cycle forward through the list while Shift + Tab will go backwards. A nifty trick is to hit the Q key while you have an Application highlighted in the Application switcher; you’ll notice that the icon fades out, the Application has just quit.

Using Mac OS X’s Dock is also an easy shortcut for quitting Applications. Right-click an open Application and choose Quit from the menu. If you’ve got an Application that has locked up and is not responding right-clicking the Application’s Dock icon will reveal a Force Quit option (much easier than opening the Force Quit window).
