Button re-mapping

Swapping two- and three-finger tap for a touchpad is a straight forward example. Instead of the default three-finger tap for pasting you can configure two-finger tap pasting by setting the TappingButtonMap option in your Xorg configuration file. To set 1/2/3-finger taps to left/right/middle set TappingButtonMap to lrm, for left/middle/right set it to lmr.

/etc/X11/xorg.conf.d/30-touchpad.conf:

Section "InputClass"
    Identifier "touchpad"
    Driver "libinput"
    MatchIsTouchpad "on"
    Option "Tapping" "on"
    Option "TappingButtonMap" "lmr"
EndSection

Remember to remove MatchIsTouchpad "on" if your device is not a touchpad and adjust the Identifier accordingly.
