我想Ctrl+Alt+b在 Emacs 中使用键绑定，但它被操作系统 (Lubuntu 22.04 LTS) 捕获。
我知道Ctrl+Alt+<left>可以通过以下方式禁用：
gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-left "['disabled']"
但我找不到使用什么值来gsettings禁用Ctrl+Alt+b。我尝试使用gsettings get org.gnome.desktop.wm.keybindings switch-to-workspace-left后跟一个TAB键，并得到以下选项。但没有人提到浏览器。

所以，
我怎样才能找到控制的程序Ctrl+Alt+b（Linux中是否有注册表或类似Emacsdescribe-key命令的东西）？
以及如何在操作系统中禁用它？
答案1
不确定是否有更通用的解决方案，但我找到了答案Lubuntu 文档。看来Ctrl+Alt-b不受控制gsettings。相反，它设置为：
lxqt-config-globalkeyshortcuts
然后在对话框中，第一个条目是Control+Alt+B“Web 浏览器”。取消选中它解决了问题。
还存在其他快捷键，例如Contorl+Alt+T用于启动终端的快捷键。
