[Macbook Pro 2014] Note that I'm running Xenial on a MacBook Pro Retina 2014
I have the Tweak Tool installed, and on the "General" tab I can set keys to zoom my desktop in/out, but I am unable to make the Tweak Tool recognise the mousewheel.
While researching this question, I eventually found that CompizConfig is needed and that the guide for Ubuntu 11.04 is still valid. (Note that button 4 is mousewheel scroll up, and button 5 is scroll down.)
It seems a bit silly that both Tweak Tool and CompizConfig allow control of the feature but only CompizConfig allows you to specify the mousewheel. Is there a way to set this through the Tweak Tool?
