 *    # Configuration manipulations
 *      1. $gameSystem.targetingHotkeys[index]
 *         - Returns the keyboard mapping of hotkey selecting the actor/enemy
 *           with the specified member index as the target
 *      2. $gameSystem.targetingHotkeys[index] = keyboardMapping
 *         - Sets the keyboard mapping of hotkey selecting the actor/enemy
 *           with the specified member index as the target as keyboardMapping
 *         - All $gameSystem.targetingHotkeys[index] changes will be saved
