Make VoiceOver ignore the next key press
Apps may use the VoiceOver modifier with another key to perform an action. If you’re using VoiceOver and want to use the app’s command, you can tell VoiceOver to ignore the next key combination.
Note: VO represents the VoiceOver modifier.
VoiceOver ignores the app command when you press it.
You can change many keyboard shortcuts for apps in the Shortcuts pane of Keyboard preferences.
