I set a new hotkey to show desktop.
$ xfconf-query --channel xfce4-keyboard-shortcuts --property "/xfwm4/custom/<Super>d" --reset $ xfconf-query --channel xfce4-keyboard-shortcuts --property "/xfwm4/custom/<Super>d" --create --type string --set "show_desktop_key"
This works until the next restart. Then the new hotkey is lost.
