Assign VoiceOver commands to gestures on Mac
Customise some VoiceOver gestures by assigning specific VoiceOver commands to them.
Note: VO represents the VoiceOver modifier. See Use the VoiceOver modifier.
Open VoiceOver Utility (press VO-F8 when VoiceOver is on), click the Commanders category, then click Trackpad.
Make sure Enable Trackpad Commander is selected, then click Assign Commands.
Click the pop-up menu, then choose a modifier key, such as Command or Shift, to use with your customised gestures.
Interact with the Trackpad Gesture Commands table, then navigate down the Trackpad Gesture column until you hear the gesture you want to customise. See Use VoiceOver to interact with areas and groups.
In the Command column, click the pop-up menu of commands, navigate the available commands until you hear the one you want, then press Return.
Use the Custom Commands menu to assign scripts and Automator workflows to gestures.
VoiceOver includes a set of standard VoiceOver gestures, which you can’t change.
