问题描述
Gnome GUI (gnome-shell) 只允许您设置一个快捷键。例如，您可以将 Super+Tab 和 Alt+Tab 设置为两个切换应用程序吗？
解决方法
是的，你可以。经验证，这适用于 Ubuntu 20.10 和 21.04RC。
以下命令可实现请求的结果：
gsettings set org.gnome.desktop.wm.keybindings switch-windows-backward "['<Shift><Super>Tab','<Shift><Alt>Tab']"
gsettings set org.gnome.desktop.wm.keybindings switch-windows "['<Super>Tab','<Alt>Tab']"
有关更多选项，请参见此处：
# list all keybindings
gsettings list-recursively | grep -e org.gnome.desktop.wm.keybindings -e org.gnome.settings-daemon.plugins.media-keys -e org.gnome.settings-daemon.plugins.power | sort
# confirm no other keybinding conflicts
gsettings list-recursively | grep '<Control>1'
# set multiple keybindings for "Switch to Workspace 1"
gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-1 "['<Super>Home','<Control>1']"
# confirm value is set correctly
gsettings get org.gnome.desktop.wm.keybindings switch-to-workspace-1
