Middle mouse emulation

From WikiDotMako

If you use a keyboard like a Unicomp Endura you might find yourself without a middle mouse button. Fortunately, you can press the left and right buttons together to emulate the behavior of pressing a middle mouse button, but only if you create or edit your xorg.conf in /ect/X11 and add the following entry:

  Section "InputClass"
       Identifier "middle button emulation class"
       MatchIsPointer "on"
       Option "Emulate3Buttons" "on"
       Option "MiddleEmulation" "on"
