 Maybe it would be enough for you just to set up PresentWindows as the effect 
for Alt+Tab? That one already has this feature.

 I assume by releasing you mean the same way Alt+Tab works, i.e. releasing all 
the keys in the shortcut, not just one. Not exactly trivial. The code for 
Alt+Tab isn't either. I suggest you simply try reusing that code, see 
tabbox.cpp, mainly areModKeysDepressed() I think.
