Use VoiceOver to perform an item’s alternate action on Mac
Menu commands and other elements, such as buttons or checkboxes, may offer alternate actions.
Show actions for menu commands
Some menu commands may offer alternate actions when you press a modifier key.
Move the VoiceOver cursor to a menu command.
Hold down a modifier key.
If the command has an alternate action associated with that modifier, VoiceOver speaks it.
To perform the action, continue to hold the modifier key and press Enter, or press the other required keys.
Show actions for user interface elements
If an app or website developer has identified alternate actions for elements like buttons or checkboxes for screen readers, VoiceOver automatically announces them, so you can show and navigate to them.
Note: VO represents the VoiceOver modifier. See Use the VoiceOver modifier.
Show alternate actions: Press VO-Command-Space bar to open the Actions menu, then choose Show alternate items.
Show default items actions: Press VO-Command-Space bar to open the Actions menu, then choose Show default items.
