• gnome-terminal Ubuntu how to disable F10 key*
    For gtk-3 apps like gnome-terminal and nautilus I created a new file:
    cat > ~/.config/gtk-3.0/gtk.css
    @binding-set NoKeyboardNavigation {
    unbind "<F10"
    unbind "<shift>F10"
    }

    * {
    gtk-key-bindings: NoKeyboardNavigation
    }

    Close all terminals these changes were in effect.
