Mouse button emulation

[a monkey <the.only.monkey@gmail.com>]

I just installed Debian Sarge on an eMac. As you know, Apple mice have 
only one mouse button, which serve as the left mouse button. But what if 
I want to right-click on something? Is there a key on my keyboard that 
will emulate the right mouse button? Any help will be greatly appreciated.

Thanks,
