After an accident that damaged my hands, I am no longer able to do the two finger scrolling gesture on Macbook touchpad. On Windows I set up so called "scrollzone", it allows me to scroll smoothly by dragging one finger along the right edge of the touchpad.
I would like to have this feature on OSX as well.
I tried many apps, namely
and none of them could do this. I even tried to contact the developers if they would be willing to work on this, but they either ignore me or say they cannot do it.
People advise me to buy a Magic Mouse, which supposedly can do it, or to scroll with arrow keys. No, thanks. I know there are workarounds available, but I know what works best for me (scrollzone) and I am unwilling to settle for less.
I would gladly sacrifice other trackpad gestures. I cannot use them anyway.
There was a program called SideTrack that could do this, but it does not work any more. I wrote to the author, but got little help.
