Scrolling with MacBook trackpad: Is it possible to do with only one finger while a key pressed? The normal way to scroll on a MacBook trackpad is to use two-finger scrolling.

Is it possible to scroll with one finger as follows:


Press and hold a key-modifier (e.g. ctrl/alt etc).
Scroll using one finger like it is two fingers, while key pressed.
What works for me is Scroll tool that allows you to enable single finger scrolling on the trackpad side. I got the idea from this superuser thread
