I can do a 2-finger swipe on my trackpad to scroll the tiles left and right in Windows 8 Modern UI, but every time I do it, it scrolls in the opposite direction I'd expect. Is there a way to reverse it?
If relevant, I'm using the Logitech K400r
I had to change this setting as soon as I started to play with Windows 8.1.
Just follow the directions laid out in this tutorial and you'll be all set.
Your Logitech device has special software utility called SetPoint which allows various adjustments of keyboard and trackpad on your device.
You can download it from K400r support page.
Since SetPoint 6.51.8 you can enable "Natural scrolling" which reverses scrolling direction.
Open SetPoint, go to Scrolling tab, click on Scrolling options and check the first option.
