+Subject: [PATCH] Optimize querying symbolic hotkeys
+
+This API is not threadsafe and there is no alternative API for querying
+whether the symbolic hotkeys have changed.
+
+Instead, we can check the last modification time of the preferences file
+and only update the symbolic hotkeys _iff_ the underlying storage file
+has changed.
