macOS High Sierra

Perform an item’s alternate action

Some menu commands may offer alternate actions when you press a modifier key.

Buttons, checkboxes, and other user interface elements can also offer alternate actions. For example, moving the pointer over a label may display additional buttons. If an app or website developer identifies these types of alternate items for screen readers, VoiceOver automatically announces them, so you can show and navigate to them.

Note: VO represents the VoiceOver modifier.

  • For menu commands: Move the VoiceOver cursor to a menu command, then 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.

  • For user interface elements: VoiceOver announces when alternate items exist. Press VO-Command-Space bar to open the Actions menu, then choose Show alternate items. To show the default items again, press VO-Command-Space bar to open the Actions menu, then choose Show default items.
