I'm not sure about the cntl-click. A Google shows a bunch of different options that may work but can't check them out today. But for scrolling you might try the advice here: http://linuxg.net/enable-horizontal-and-natural-scrolling-in...

It looks like the GUI shows options for both devices, but the settings are split between trackpad and device. So it may do what you want.

I attempted Linux on a Chromebook Pixel and it was miserable, which is why I had shied away from the Retina. :-)
