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?

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.
