Change Shortcut preferences for accessibility on Mac
On your Mac, use the Shortcut pane of Accessibility preferences to change the options included in the Accessibility Options shortcut panel. The shortcut panel (shown when you press Option-Command-F5 or, if your Mac has Touch ID, when you quickly press Touch ID three times) is a quick way to turn the options you use most often on or off.
To change these preferences, choose Apple menu > System Preferences, click Accessibility, then click Shortcut.
List of options
Select the checkboxes for the options you want to include in the Accessibility Options shortcut panel. If you don’t want to include an option, deselect its checkbox.
If you select only one option, the shortcut 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.
