lets say the user had been resizing the window without any modifier keys pressed, but then realized what s/he really wanted was to resize in only one dimension or to maintain the window’s aspect ratio, so now s/he presses either shift or shift and control. i would like to be able to resize the window at this time to show the proper effect, but i can’t do this until the user moves the mouse AFTER changing the modifier keys.

That is, your override would not reimplement or otherwise interfere with -nextEvent..., it would just monitor what it's returning.
two immediate comments though:
in the override you suggest, i will have to “or” in the NSFlagsChangedMask to make sure i get the changes as the framework’s event loop may (i don’t know) be only looking for mouse down or mouse moved events. and
the framework may be using -nextEventMatchingMask: instead of -nextEventMatchingMask:untilDate:inMode:dequeue:
i will experiment and report back.
thanx for the suggestion,
