Flashing the screen

[Brent Anderson]

Hello.

In HyperCard there is a command for "Flashing" the screen (Inverting  
it x amount of times). I've gotten a script to work that creates a  
button with an inverted ink, and then shows it and hides it x amount  
of times. The only problem with it is that on many computers i've  
tried it on, it is too slow to look cool. On Mac OS X (The platform I  
need this script for), there is a key stroke you can use if you have  
issues seeing things on the screen. You press Command + Option +  
Control + 8, it will invert the screen. Would there be any way that  
you could pass that to the system, or is it impossible?

Thanks,
Brent Anderson
