If you’re using VoiceOver gestures, drag a finger across the trackpad to navigate the areas and menus in the menu bar. You hear a sound effect when moving over a blank space. You can also flick left or right to move between menus.
Open any menu: Press VO-Space bar.
Move up or down a menu: Press VO-Down Arrow or VO-Up Arrow, or drag a finger down or up on the trackpad.
Move to a submenu: Press VO-Right Arrow or flick right on the trackpad. To return to the main menu, press VO-Left Arrow or flick left on the trackpad.
To exit a menu without selecting an item, press Escape, or scrub back and forth with two fingers on the trackpad.
To open a shortcut menu for an item, press VO-Shift-M, or use the customised gesture Control-Trackpad click (you can change this default assignment and assign the command to a different gesture).
