Use VoiceOver to select and deselect items on Mac
Select or deselect a single item or multiple items.
Note: VO represents the VoiceOver modifier.
Select an item: Press VO-Return.
Deselect an item: Press VO-Command-Return, or double-tap on the trackpad.
Select multiple items: Start interacting with a list or table, navigate to the first item, then press VO-Command-Return (this action temporarily turns cursor tracking off). For each additional item, navigate to it, then press VO-Command-Return. To stop selecting items, press the Escape key or Fn-Tab, or stop interacting with the list or table (this action turns cursor tracking on).
Deselect items: Navigate to an item, then press VO-Command-F4. VoiceOver deselects all items except the one in the VoiceOver cursor. To deselect that item, press VO-Command-Return.
