Using the keyboard: Press Fn + Alt + Cmd + F5 (Note: You can omit the Fn (function) key if you are using the F keys as standard function keys).
Using Touch ID (if available on your computer): Triple-press the Touch ID button.
Select the Preferences button to open the Accessibility preferences window.
On the Accessibility preferences window, scroll to the bottom of the left-hand column and select Shortcut.
In the right column, tick the checkboxes for all the items you want to appear in the Accessibility Options menu. Untick the checkboxes for all the items you don’t want to appear in the menu.
When you have finished, click the Close (red) button in the top left corner of the System Preferences window.
Note: If this does not work, it could be because someone else manages your computer settings (an IT department or administrator). If this is the case, you will need to contact them to access these settings or for further help.
