Hidden Key Bindings? (Specifically Ctrl+Alt+D and Shift+Super+!)

Question

I'm trying out Gnome on the newest version of Ubuntu and it seems that there are 'secret' key bindings. For example, Ctrl+Alt+D minimizes all my windows and Shift+Super+! Opens the first program in my dock. Under the settings and gconf-editor I cannot find these keybindings. Ctrl+Super+D also minimizes my windows but it shows that in the settings. Where can I find and edit all my key bindings? Specifically, how can I change the two key bindings previously mentioned? Thank you.

Answer 1

There is some mystery, but it may be revealed:

• Ctrl+Alt+D is defined in /org/gnome/desktop/wm/keybindings/show-desktop (check in dconf-editor):

  

  but Ctrl is named <Primary> here. So we can find them in gsettings:

  gsettings list-recursively | egrep "Primary.*Alt.*d"
  org.gnome.desktop.wm.keybindings show-desktop ['<Primary><Super>d', '<Primary><Alt>d', '<Super>d']
  

• Shift+Super+! (or more precise Shift+Super+1)

  seems to be secret - are shown in dconf-editor and in gsettings:

  gsettings list-recursively  | grep -i shift.*super
  org.gnome.shell.extensions.dash-to-dock app-shift-hotkey-10 ['<Shift><Super>0']
  org.gnome.shell.extensions.dash-to-dock app-shift-hotkey-1 ['<Shift><Super>1']
  org.gnome.shell.extensions.dash-to-dock app-shift-hotkey-2 ['<Shift><Super>2']
  org.gnome.shell.extensions.dash-to-dock app-shift-hotkey-3 ['<Shift><Super>3']
  org.gnome.shell.extensions.dash-to-dock app-shift-hotkey-4 ['<Shift><Super>4']
  org.gnome.shell.extensions.dash-to-dock app-shift-hotkey-5 ['<Shift><Super>5']
  org.gnome.shell.extensions.dash-to-dock app-shift-hotkey-6 ['<Shift><Super>6']
  org.gnome.shell.extensions.dash-to-dock app-shift-hotkey-7 ['<Shift><Super>7']
  org.gnome.shell.extensions.dash-to-dock app-shift-hotkey-8 ['<Shift><Super>8']
  org.gnome.shell.extensions.dash-to-dock app-shift-hotkey-9 ['<Shift><Super>9']
  

• Ctrl+Super+D

  is defined in GNOME Control Center → Keyboard (gnome-control-center keyboard) and in dconf-editor (see above):

  

  and in gsettings:

  gsettings list-recursively | egrep "Primary.*Super.*d"
  org.gnome.desktop.wm.keybindings show-desktop ['<Primary><Super>d', '<Primary><Alt>d', '<Super>d']
  

Conclusion:

1. all stuff is shown in gsettings. But <Ctrl> is named <Primary>.
2. all this stuff looks more and more like RegEdit in some other operating system.
