/schemas/desktop/gnome/shell/windows/attach_modal_dialogs /desktop/gnome/shell/windows/attach_modal_dialogs gnome-shell bool true Attach modal dialog to the parent window This key overrides /apps/mutter/general/attach_modal_dialogs when running GNOME Shell. /schemas/desktop/gnome/shell/windows/button_layout /desktop/gnome/shell/windows/button_layout gnome-shell string :minimize,maximize,close Arrangement of buttons on the titlebar Arrangement of buttons on the titlebar. The value should be a string, such as "menu:minimize,maximize,spacer,close"; the colon separates the left corner of the window from the right corner, and the button names are comma-separated. Duplicate buttons are not allowed. Unknown button names are silently ignored so that buttons can be added in future gnome-shell versions without breaking older versions. A special spacer tag can be used to insert some space between two adjacent buttons. This key overrides /apps/metacity/general/button_layout when running GNOME Shell.
