Inspiron 5559 - can I turn off the click sound for the touchpad buttons?

I'm a big-time right-click and open in new tab user, but having the buttons "hard-click" sound every time I click on something is going to drive my housemates nuts.  

Any suggestions out there?  Thanks.

My only suggestion is to just tap the scroll pad above the buttons, it basically does the same thing unless you are doing a copy and paste.

Found it.  Took some digging, but a two-finger tap is apparently the trick.  Weird that the touchpad doesn't support left-click and right-click by where you tap the touchpad.  

Thanks.
