To make this work, you’re going to need to make sure that you’ve got AutoHotkey installed, or else the script won’t work. Don’t worry, it’s really lightweight.

Once you’ve got that installed, you can either paste this into a new AutoHotkey script (a *.ahk file), or put it into your existing script. Or you could just download the script I’ve got linked below.

Save it, double-click the file to run it, and you’ve now got reverse scrolling. Or, you know, just download it.
