How to toggle mirroring of external display for Macbook Pro touch bar? Command + F1 does not work anymore.
I used use the short key F1 + Command to toggle external display mirroring but after
upgrading to Macbook Pro 13" touch bar(late 2016) it does not work any more.
Keyboard system preference "Use all F1, F2, etc. keys as standard function keys,"
option was removed.
I use Macbook Pro with Epson 345 projector for my lecture. Toggling through mirroring
at the system preference display is very time consuming. Any suggestion?
MacBook Pro (13-inch, Late 2016, 4 TBT3), mac OS sierra 10.12.3
