1) The Carbon key modifiers parameter is a UInt32, not a UInt16. Never try to
extract the key modifiers parameter from a Carbon Event into an EventModifiers

2) The Carbon key modifiers is just that: key modifiers. That parameter will

* GetCurrentEventKeyModifiers is much faster than
* GetCurrentKeyModifiers because it returns the locally cached
* modifier state; GetCurrentKeyModifiers must get the modifier
* state from the window server, which is slower. Using
* GetCurrentKeyModifiers also can prevent your application from
* being operated by remote posting of events, since the hardware
* input device is not actually changing state in that case. Most
* commonly, you might need to use GetCurrentKeyModifiers when your
* application is not the active application (as determined by the
* Process Manager function GetFrontProcess). In that case, the
* cached modifier state returned by GetCurrentEventKeyModifiers is
* not valid because modifier-changed events are not flowing to your
* application, and you must use GetCurrentKeyModifiers to determine
* the current hardware state.
*
* Result:
* The hardware state of the keyboard modifiers. The format of the
* return value is the same as the modifiers field of an EventRecord
* (but only includes keyboard modifiers and not the other modifier
