Quickly quit programs using the Application Switcher
The Mac OS X Application Switcher is a handy way to quickly cycle through open applications, but did you know you can quickly quit programs you aren’t using with the Application Switcher as well?
* Enter the Application Switcher by hitting Command+Tab
* Using tab or your mouse, navigate to the application(s) you want to quit while still holding the Command key
* Press “Q” to quit the application that you are hovered over
This is just one of many cool tricks you can do with the Command+Tab application switcher.
