Chapter 8. Configuring, Customizing, and... > Controlling Open Applications

Controlling Open Applications

Mac OS X provides several ways to control open applications.

  • You can switch among open applications by clicking the icon of the open application to which you want to switch on the Dock or by using the +Tab or Shift+ +Tab keys (the currently selected application's icon will be highlighted on the Dock as you press the +Tab or Shift+ +Tab key combination). If the Dock is hidden, it will appear when you use these keys.

  • Hide applications quickly by pressing +H or by choosing the Hide command on the application's Application menu.

  • Quit an open application by holding down the Control key while clicking the application's icon on the Dock. From the pop-up menu, choose Quit.

  • There are several ways to force a hung application to quit. Press Option+Command+Esc to open the Force Quit Applications window, choose the application you want to quit, and click Force Quit (see Figure 8.9). (If an application is hung, its name will appear in red in the Force Quit Applications window.) Open the Process Viewer application (Applications/Utilities), select the application you want to quit, and choose Processes, Quit Process (or press Shift+ +Q). Use the Unix kill command along with the process number of the application you want to force to quit.

    Figure 8.9. You can force an application to quit by opening the Force Quit Applications window, selecting the application you want to quit, and clicking Force Quit.
