macOS High Sierra

Use an app full screen

Many apps in macOS, such as Mail, let you expand the window to fill the screen.

Note: VO represents the VoiceOver modifier.

  • To enter full screen in an app that supports it, press Control-Command-F. You can also navigate to the green full-screen button in the top-left corner of the app window, then press Command-Space bar.

    The full-screen button can also expand (or maximize) the window. To do so, navigate to the button, press VO-Command-Space bar to open the Actions menu, then choose “zoom the window.” To return the window to its previous size, navigate to the full-screen button, press VO-Command-Space bar to open the Actions menu, then choose “zoom the window.”

  • When you work full screen, the menu bar is displayed only when the pointer moves there. To navigate to the menu bar to display it, press VO-M.

  • To exit full screen, press VO-F2-F2 to display the Window Chooser, press the Down Arrow or Up Arrow key until you hear “Exit full screen,” then press the Space bar. Or press Control-Command-F.
