My home computer is a Mac, now running OSX Lion. I’ve become quite accustomed to the backwards/reversed scrolling which seems to be the default in Lion – and matches the “natural” swipe up/down gestures you would use on an iPhone or other touch screen device.

Today I was looking around on my work Windows XP machine, and was disappointed to find there is no “invert mouse” option.

So I found this – http://www.howtogeek.com/57542/how-to-get-the-worst-os-x-lion-feature-in-windows-reverse-scrolling/

Setting Up Reverse Scrolling in Windows

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 we’ve got linked below.

WheelUp::
Send {WheelDown}
Return

WheelDown::
Send {WheelUp}
Return

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