Use VoiceOver in Mission Control on Mac
Mission Control shows all of the windows open on the desktop (VoiceOver calls them exposéd windows), neatly arranged so it’s easy to find the one you need. Apps that are in full screen or Split View, and desktop spaces you created, are shown in the Spaces bar (VoiceOver calls it the spaces list) along the top edge of the screen.
Note: VO represents the VoiceOver modifier. See Use the VoiceOver modifier.
Enter Mission Control by pressing Control-Up Arrow.
To exit Mission Control without doing anything, press the keys again.
In Mission Control, do any of the following:
Open an item in a window group: Press VO-Left Arrow or VO-Right Arrow to navigate to the group, press VO-Shift-Down Arrow to interact with it, navigate to the window, then press VO-Space bar.
Open an item in the spaces list: Press VO-Left Arrow or VO-Right Arrow to navigate to the list, press VO-Shift-Down Arrow to interact with it, navigate to the item, then press VO-Space bar.
Create a desktop space: Press VO-Left Arrow or VO-Right Arrow to navigate to the Add Desktop button in the spaces list, then press VO-Space bar.
Remove a desktop space: Press VO-Left Arrow or VO-Right Arrow to navigate to the spaces list, press VO-Shift-Down Arrow to interact with it, navigate to the space, then press VO-Command-Escape. Press Return to confirm.
You can easily move between desktops while you’re working—just press Control-Right Arrow or Control-Left Arrow.
