 832      *
 833      * If one of the keys corresponding to a flag is down, we rely on

 835      * NSEventTypeFlagsChanged to know the exact key which is down, which has

 838      * - It malfactions *after* the modifier state is changed while the

 840      *   if the key is up or down, and requires to infer the current state from
