+Subject: Disable keybindings message should ungrab keys
+
+The disable-keybindings action is currently only 'soft' in that it
+just causes Metacity to ignore keypresses; the keys themselves are left
+bound.
+
+Sugar would like to use this message to actually disable the bindings
+*and* release the grabs so that it can implement its own Alt-Tab handler.
+
+This patch implements this. Based on earlier work by Bernie Innocenti.
