Detaching audio in FCPX 10.4.10
In the drop down menu 'detach audio' is listed as -
^ , and an arrow I can't add here, S
In the FCP help it says -
Option-Command-B
On my iMac running Mojave 10.4.6 neither works and I have to use the drop down menu.
Why is this - perhaps a fault with my machine. What is the correct key combination for this regularly used feature?
I note also that Apple should update their 'help' as several things have been altered now. They owe it to customers who paid for an expensive programme.
