Change Shortcut settings for accessibility on Mac
On your Mac, use Shortcut settings for accessibility to change the options included in the Accessibility Shortcuts panel. The panel (shown when you press Option-Command-F5 or, if your Mac or Magic Keyboard has Touch ID, when you quickly press Touch ID three times) is a quick way to turn on or off the options you use most often.
To change these settings, choose Apple menu > System Settings, click Accessibility in the sidebar, then click Shortcut on the right. (You may need to scroll down.)

List of options
Options included in the Accessibility Shortcuts panel. To include an option, select its checkbox; if you don’t want to include an option, deselect its checkbox.
If you select only one option, the panel isn’t displayed when you press Option-Command-F5 or press Touch ID three times; instead, the option is immediately turned on or off.
