My understanding is that the modifierFlag "256" means that no other
modifiers are pressed. I haven't found it in the docs anywhere, but I
believe that you can count on "256" meaning "no flags". Every machine I've
tested this on (I've done a bunch of CGEvent stuff recently) seems to agree.

Unsafe assumption. You are just lucky that some lower bit (device dependent bit) is being set for you. I know of no documentation that says this bit will always set. Additionally if some other device dependent bit is set your assumption would be broken.
