Control-D no longer works
The clip duration menu and the Control-D keys combo no longer work. I've got the latest versions of Ventura and FCP and the Mac is a M1 Studio with 64 Gb of RAM. So far, I've trashed the preferences (at FCP startup and, to be sure, by killing the plist in Library/Preferences). I've restarted FCP and Ventura a few times. I've trashed FCP and reinstalled it from the Appstore. I even changed the keyboard. And, of course, I've used some profanities. All in vain. No matter what FCP library I try, no matter on what drive it is, Control-D refuses to work as well as the right-clic menu. FYI I've been using FCP since 2012 with which I've signed over 150 features (between 20 and 90 minutes each) as a director and editor. What's happening now, I've never experienced before and I've found no useful ressource on the Internet.
Has someone any clue ? Thank you for helping.
