Ubuntu: Modifying Key- and Mouse-Bindings for GNOME Shell



Question:

Is there an easy way to modify key- and mouse-bindings for GNOME shell? The gnome-tweak-tool is far from complete regarding these issues and the system settings doesn't include any such options. I guess there is always the possibility of opening the [gd]conf-editor. If that is our final resort for now what key patterns are involved then?


Solution:1

To change the keyboard bindings, find the keyboard section in the system settings application. Under the shortcuts tab, find the shortcut that's called something like "Go into Overview Mode." Then you can change it to whatever you want.

To disable hot corner, see this question.


Solution:2

All keyboard shortcuts are configured via system settings/keyboard/shortcuts. Overlay mode can be activated with keybinding "show main menu". There're no mouse-bindings.

Under the hood.

Standard keyboard shortcuts are stored at:

gconf:///apps/metacity/global_keybindings  gconf:///apps/metacity/window_keybindings  

Modifier to manipulate windows (drag, popup menu) is at:

gconf:///apps/metacity/general/mouse_button_modifier  

Shortcuts to launch browser/email/etc at:

dconf:///org/gnome/settings-daemon/plugins/media-keys  

Key to enter overview mode is at:

gconf:///apps/mutter/general/overlay_key  

The option value is keysym (as given in xkb-config or ~/.Xmodmap), you may put "Menu" here to use menu-key to launch overview. When assigned to other keys it may behave weird.


Solution:3

You can find all the keybindings used by Gnome Shell at the dconf location org.gnome.desktop.wm.keybindings
