CTRL-F9 (passthrough toggle)

[olivaw]

I've read that the keypress combination CTRL-F9 can be used to toggle the passthrough function on Voodoo2 cards.  This would be useful to get back to the desktop when a Glide program crashes, for instance.  Of course this doesn't work under Windows XP.  Does anyone know of a small program that could be used to accomplish the same thing?

Thanks
