how to change double click as the middle button

[lina <lina.lastname@gmail.com>]

Hi,

Originally I have  xserver-xorg-input-synaptics, which I used the double
click as the middle button. Three clicks as the right button,

The 50-synaptics.conf is under /etc/X11/xorg.conf.d/


In my situation, I installed a new kernel, which seems that the new
kernel use the bcm5974 to determine the behavior of the mouse, which
ignores the synaptic setting,

I wish to come back to the old days use the double tap as the middle
button, any suggestions, thanks.
