[TriLUG] third mouse button

[Richard O. Hammer]

What's the use of the third mouse button?

When I started using Linux earlier this year, I made it a
point to buy a three-button mouse.  I had the impression that
was standard in the Unix world.  But I think I've never seen
an application yet which called for that third button.

Would I be cutting myself off from some important future
functionality if I set up a Linux system with only a
two-button mouse?

Thanks,
