Mac OS X tip: Navigating open applications

Here are some quick shortcuts for navigating open applications in OS X that will save you a few mouse clicks. You probably know all about switching between applications with Command-Tab, but you may no know that you can hide and close applications too:

• If you want to close an app, hit “Q” when it’s highlighted
  
• If you just want to hide an app, hit “H” when it’s highlighted.
• If you decided you want to stay in the app you had active when you invoked Command-Tab, hit ESC.
