/* 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.
