如何扩展Ctrl+Alt+B (用于打开浏览器)？

Question

我想在Emacs中使用键绑定Ctrl+Alt+b，但它是由操作系统(Lubuntu22.04LTS)捕获的。

我知道可以使用以下方法禁用Ctrl+Alt+<left>：

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

但是我找不到在gsettings中使用什么值来禁用Ctrl+Alt+b。我尝试使用gsettings get org.gnome.desktop.wm.keybindings switch-to-workspace-left，后面跟着一个TAB键，并获得了以下选项。但没有人提到浏览器。

所以,

如何找到控制Ctrl+Alt+b的程序(在Linux中是否有类似Emacs describe-key命令的注册表或其他东西)？

以及如何在操作系统中禁用它？

Answer 1

不确定是否有更通用的解决方案，但我从Lubuntu文档那里找到了答案。Ctrl+Alt-b似乎不是由gsettings控制的。相反，它被设置为：

lxqt-config-globalkeyshortcuts

然后在对话框中，第一个条目是"Web“的Control+Alt+B。不检查它解决了问题。

此外，还有其他快捷键，如用于发射终端的Contorl+Alt+T。
