Root terminal keyboard shortcut in focused VM
Using i3 there is an way how to open terminal in the VM of the focused window ($mod+Enter by default).
Sometimes you’d want to be root in that terminal easily. You can define yet another keyboard shortcut to do so ($mod+Shift+Enter in the following example).
in dom0:~/.config/i3/config:
bindsym $mod+Return exec qubes-i3-sensible-terminal
bindsym $mod+Shift+Return exec qubes-i3-sensible-terminal.root
