Ctrl+Alt+B(브라우저 시작에 사용)를 비활성화하는 방법은 무엇입니까?

Emacs에서 키 바인딩을 사용 하고 싶지만 Ctrl+Alt+b운영 체제(Lubuntu 22.04 LTS)에 걸렸습니다.

Ctrl+Alt+<left>다음을 통해 비활성화할 수 있다는 것을 알고 있습니다 .

gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-left "['disabled']"

gsettings하지만 비활성화 하는 데 사용할 값을 찾을 수 없습니다 Ctrl+Alt+b. 나는 키를 사용하여 gsettings get org.gnome.desktop.wm.keybindings switch-to-workspace-left다음 TAB과 같은 옵션을 얻었습니다. 그러나 아무도 브라우저에 대해 언급하지 않았습니다.

그래서,

제어 프로그램을 어떻게 찾을 수 있습니까 Ctrl+Alt+b(Linux에 레지스트리나 describe-keyEmacs 명령과 같은 것이 있습니까)?

운영 체제에서 이를 비활성화하는 방법은 무엇입니까?
