Hi! I am on macOS Catalina and am trying to change the copy-paste combination on my keyboard from Command+C and Command+V to Control+C and Control+V, respectively. Under Settings > Keyboard > Shortcuts > App Shortcuts, I already have a copy-paste setting for 'All Applications', and it works on ALL applications I tested with (Google Chrome, Safari, Telegram, terminal emulators, etc.), EXCEPT on Firefox. So then I tried to add a custom setting for Firefox.app. Copy works: I can CTRL+C in a firefox page and CTRL+V on another app. BUT CTRL+V does not work in Firefox itself -- the previous shortcut Command+V is what still works. What should I do so that: # Numbered list itemFirefox will use the app shortcuts for 'All Applications' instead of having its own configuration (less important) # Bulleted list itemCTRL+V would work on Firefox? (more important) My Firefox version is 85.0.2 Thanks in advance. ++ Edit, additional info: I followed the list of valid command names at https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly?redirectslug=Keyboard+shortcuts&redirectlocale=en-US#w_bookmarks. Adding some of them to 'App Shortcut' works (such as New Tab, Close Tab, and Bookmark This Page), and some of them don't (such as Find in This Page and Find in This Page).
