Enabling “Emulate3Buttons”

I really love to use trackball but there is no middle button on my Logitech trackball to do the copy and paste.

In order to do so with holding down both left and right button, just add a section to /etc/X11/xorg.conf:

 Section "InputClass"
     Identifier "middle button emulation class"
     Option "Emulate3Buttons" "on"
 EndSection

Then restart the window manager.
