Can't find Alt-F5 in Settings/Keyboard Shortcuts
Solution 1:
"Restore", which is found in the Windows section in Settings - Keyboard shortcuts, is not only assigned to Super+Down, but also to the "traditional" shortcut Alt+F5. You can disable the binding to Alt+F5 and retain the Super+Down binding with the following command in the terminal or in the run dialog (Alt+F2):
gsettings set org.gnome.desktop.wm.keybindings unmaximize "['<Super>Down']"
That removes the assignment to Alt+F5, but maintains Super+Down for unmaximizing a window. Reset to the default (['<Super>Down', '<Alt>F5']
) with the command
gsettings reset org.gnome.desktop.wm.keybindings unmaximize
You can edit this and many other "hidden" settings using dconf-editor
, not installed by default.
