Option	Description
Use keyboard shortcuts to zoom	Use the listed shortcuts to zoom in or out. For example, to zoom in, press Option-Command-Equal Sign.
Use scroll gesture with modifier keys to zoom	Press and hold the selected modifier key while scrolling with your trackpad or the scroll wheel on your mouse. For example, with the default trackpad settings, press and hold the Control key and drag two fingers up (to zoom in) or down (to zoom out).
Zoom Style	Choose to zoom the entire screen (Full screen), a custom area of the screen (Split screen), or just the area where the pointer is located (Picture-in-picture). When you use full-screen zoom, you can zoom the screen of an available second display (sometimes called Zoom Display). Click Choose Display, then choose a display.
Advanced	Specify options for the selected zoom style.
Enable Hover Text	Display a high-resolution zoom of text, text fields, menu items, buttons, and more in a dedicated window. See Use Hover Text. To customize Hover Text, click Options, then set any of the following options: Text size and Text font: Choose the size and font for text shown in the Hover Text window. By default, the font is the same as your system font. Text-entry location: Choose the position of the Hover Text window when you enter text—for example, you can position it near the line where you’re entering text or at the bottom left of the screen. To set your own position, choose Custom, then drag the window to where you want it shown. If you don’t want the window shown when you enter text, choose None. Activation modifier: Choose the modifier key to press to activate Hover Text. Activation lock: Keep the Hover Text window on the screen. When you need the window shown for a period of time—for example, when filling out a form—quickly press the selected modifier key three times. To stop showing the window, quickly press the key three times again. Colors: Specify the text color used in the Hover Text window, and colors for the window itself.
Enable Touch Bar zoom	If your Mac has a Touch Bar, display a larger version of it on the screen. See Zoom in on the Touch Bar.

To quickly enable or disable Zoom using the Accessibility Shortcuts panel, press Option-Command-F5 (or if your Mac or Magic Keyboard has Touch ID, quickly press Touch ID three times).

To specify which options are available in the panel, choose Apple menu > System Preferences, click Accessibility, then click Shortcut.
