Detecting right mouse button in LSL?

Ok, this probably sounds hokie, but this is what I want to do:
You know how in SL when you click the right mouse button you get a beam of light balls that shoot from your hand to whatever your cursor is on? What I'd like to do is create a ring attachment (or something) that monitors for whenever the right mouse button is clicked (not clicked on the ring, just any right mouse button click that the user does) and when a right mouse button click is detected, the ring will generate a glow or some magical effect. I can do all of this within a script now, except for the part about monitoring for the right mouse button.

Can this even be done with LSL?

Thanks!

I do not believe that what you want to do can be done... If you look at the LSL Wiki entry on llTakeControls, you will see that of all of the controls available, the right mouse button does not appear in the list.

Ah, I figured as much. Ah, well, it was just a thought. I was really hoping I could have my avatar's hand glow whenever he started to build... like a magician conjuring things out of thin air! LOL!

Thanks!
