This is just a MacOS "feature": unlike the other platforms, it doesn't
send events when these modifier keys are pressed. Even the keyUp
message is a hack on MacOS, due to a design flaw deep inside the OS:
if there's a context switch (i.e., another program gets a chance to
run) between when the key is pressed and when it is released, the "up"
event sometimes gets sent to that other program! So what the MacOS
engine actually does is to send the keyUp message at the end of the
keyDown event handler :-(
