Trackpad Switch primary/secondary buttons and paste on double-tap?

[lowry]

Hello,

I am left-handed and an old-time Linux user.

As a left-handed, I'd like to switch primary and secondary button.

As an old Linux user, I'd like to have the select on single-finger double tap and paste on double -finger tap. The default configuration seems to link the single-finger tap and the double-finger tap to the primary button (button 1), and the triple-finger tap to the middle button (button 2). Once I invert primary and secondary buttons with 

Code:

xinput set-button-map 7 3 2 1

then the single-finger tap and the double-finger tap are also sending "button 3".

Is there a way to decouple double-tap, single-finger and double-finger tap in trackpad configuration?
