Find the accessibility menu
The accessibility menu is where you can turn on some of the accessibility settings. You can find this menu by clicking the icon which looks like a person surrounded by a circle on the top bar.
If you do not see the accessibility menu, you can enable it from the Accessibility settings panel:
Go to the desktop and start typing Accessibility.
Klik op Toegankelijkheid om het paneel te openen.
Switch the Always Show Accessibility Menu switch to on.
To access this menu using the keyboard rather than the mouse, press Ctrl+Alt+Tab to move the keyboard focus to the top bar. A white line will appear underneath the Activities button — this tells you which item on the top bar is selected. Use the arrow keys on the keyboard to move the white line under the accessibility menu icon and then press Enter to open it. You can use the up and down arrow keys to select items in the menu. Press Enter to toggle the selected item.
