In this podcast from his series looking at some of what's new and notable in iOS 15, Thomas Domville Shows us VoiceOver's new Quick Settings feature.
Activated with a 2-finger quadruple tap, the Quick Settings panel offers fast and easy access to a number of VoiceOver's settings and options, allowing you to streamline the VoiceOver rotor.
Quick Settings Keystroke For External Keyboard Users
you can also bring up the Quick Settings screen with VoiceOver+V. This command will be familiar to Mac OS VO users, as it’s the same command to adjust VoiceOver verbosity on the fly.
no braille display command for this
Sadly, Apple didn't give us a braille keyboard command for this, and there is also no way to assign one. Using the keyboard commands to emulate VO+V doesn't work either.
Not able to remove language and braille table from the rotor
As demostrated in the podcast, I have made sure these items are on quick settings. Now when I proceed to remove them from rotor, in VO settings under Accessibility, the Language option is dimmed and nothing can be done about it, while Braille Table is unselected, yet shows up among the rotor item.
