In the toolbar, press VO-Right Arrow until you hear “view radio group,” then interact with that control. Press VO-Right Arrow until you hear the view (such as Icon or List) you want to use.
When you have selected a view, stop interacting with the view radio group and the toolbar, then press VO-Right Arrow to move through the window until you hear “sidebar.”
Interact with the sidebar, then move down the list of items in the sidebar by pressing VO-Down Arrow. When you hear the item you want, press VO-J to jump to it in the view browser, where you can interact with it.
To jump if you’re using VoiceOver gestures, keep a finger on the trackpad while you press the Control key.
Move to and select the item you want to open, using the method for the view you’re in:
Icon view: Use the arrow keys to move to the item you want.
List view: To move down the list rows, press VO-Down Arrow. To expand and collapse a folder, press VO-\. To move the VoiceOver cursor across a row and hear information about an item, press VO-Right Arrow. Or press VO-R to hear the entire row read at once.
Column view: To move down the list until you find the folder or file you want, use the Down Arrow key. To move into subfolders, press the Right Arrow key.
Gallery view: To move between the gallery to the preview panel, press the Left Arrow or Right Arrow key. Interact with the gallery or the preview panel to hear its contents.
When you find the file or folder you want to open, open it using the Finder shortcut Command-O or Command-Down Arrow.
VoiceOver announces when you have selected an alias or a file or folder you don’t have permission to open.
Open the selected item: Press Command-O or Command-Down Arrow.
Move to the parent of the selected item (such as the folder that contains a subfolder you selected): Press Command-Up Arrow.
