MBP Touch Bar Mirror Displays Keyboard Shorcut

On the new macbooks with the Touch Bar, what keyboard shortcut can be used to mirror displays?

On Macbook Pros without the touchbar, the keyboard shortcut for mirroring displays was Command+F1. This doesn't seem to work on the new Macbook Pro with touchbar - you have to press the Fn key to show the F1, F2, etc. keys, and Fn+Command+F1 doesn't seem to do it.

Here are my current keyboard settings:

The new shortcut is Command-Dim Brightness. It even makes sense in the following way:

Assuming that you take advantage of the touch bar, and it displays the system controls instead of the function keys then the hand gesture is exactly the same as before when you would have pressed Command-F1 since the Dim Brightness button is where F1 would be:

The annoying thing is that if you have an application-aware touch bar configuration, then you have to bring up the system controls touch bar configuration first.

This is why, in some cases, the Display Menu (in the App Store) which adds a status item in your menu bar (and includes a Mirror Screen choice) is a good option.

Workaround found, works for me, late 2016 MBP 15":

System Preferences > Keyboard > Press Fn key to > "Show control strip"

fn + Command + "screen brightness less" (where F1 would be otherwise) = toggle mirroring
