OS X Mountain Lion: Zoom content on the screen
If you have difficulty seeing or reading items on the screen, you can use Accessibility preferences to magnify items on the screen. You can zoom the entire screen or zoom the area that has keyboard focus in a separate window.
Set up zoom
- Choose Apple menu > System Preferences, click Accessibility, and then click Zoom.
- Do either of the following:
To zoom with keyboard shortcuts, select “Use keyboard shortcuts to zoom.”
To zoom with your mouse or trackpad, select “Use scroll gesture with modifier keys to zoom.”
- Choose where the magnified content appears with the Zoom Style pop-up menu.
To display it in a window near the mouse cursor, choose Picture-in-picture. To display it on the entire screen, choose Fullscreen.
- To set options for zoom or the zoom window, click More Options.
You can also turn on zooming by pressing Command (⌘)-Option (⌥)-F5 and selecting options in the Zoom section.
Zoom with keyboard shortcuts
To zoom in, press Command (⌘)-Option (⌥)-Equal Sign (=). To zoom out, press Command (⌘)-Option (⌥)-Minus Sign (-).
If you chose Picture-in-picture zooming, a window appears near the mouse cursor with the magnified image. If you chose the Fullscreen zooming, the entire screen displays the magnified image.
Zoom with a mouse or trackpad
To zoom in and out, hold down the modifier key you specified while you perform the scroll gesture.
For example, if you have a trackpad and used the default settings, zoom in by holding down the Control (^) key while you drag two fingers up on the trackpad. Zoom out by holding down the Control key while you drag two fingers down on the trackpad.
If you chose Picture-in-picture zooming, a window appears near the mouse cursor with the magnified image. If you chose Fullscreen zooming, the entire screen displays the magnified image.
