+/* NOTES
+ *
+ * There are two sources of keybindings changes, from MateConf and from
+ * the accel map (happens with in-place menu editing).
+ *
+ * When a keybinding mateconf key changes, we propagate that into the
+ * accel map.
+ * When the accel map changes, we queue a sync to mateconf.
+ *
+ * To avoid infinite loops, we short-circuit in both directions
+ * if the value is unchanged from last known.
+ *
+ * In the keybinding editor, when editing or clearing an accel, we write
+ * the change directly to mateconf and rely on the mateconf callback to
+ * actually apply the change to the accel map.
