If it wouldn't do that, you could f.ex. trigger two emulated key 
combinations at once, ending up triggering a third, unwanted action.

In fantasy app, i.e. Apple + P could equal to "Play/Pause" and Shift 
to "some temporary display action". Together, they'd end up as Apple + 
Shift + P, which in that example could mean something totally 
undesirable like "delete current entry and file without further 
security request".

I'm looking into solutions to satisfy both desktop application and 
gaming needs, though.
