Disable trackpad two fingers + double tap with third finger bringing up Alt-Tab menu

Question

Ubuntu 14.04.1 LTS on a Macbook Air. Using exactly two fingers on the trackpad, then double tapping with either third finger brings up the same menu as Alt-Tab does.

Is it possible to turn off this shortcut?

Answer 1

Apparently I was triggering 3 finger tap.

The solution as posted by rupert here was to run:

synclient ClickFinger3=0
synclient TapButton3=0

If this does the trick (or a variance of 0 , 1 , 2, 3 , ) you can add it to startup.

Specifically for me (Macbook Air 3,1 or 3,2), the following worked:

synclient ClickFinger3=0
synclient TapButton3=1
