One of the most discussed features of Mac OS X 10.7 Lion is the “backward scrolling” that, in an attempt to resemble the behavior of iOS devices, is enabled by default in System Preferences. In the Lion Developer Preview (both 1 and 2), if you move your fingers down the screen scrolls up, and vice versa. This is activated by default to make iOS users feel comfortable when using the new desktop OS, but has annoyed several long-time OS X users as the preference is automatically enabled and is buried deep down into the Trackpad settings as a checkbox.
If you believe, however, that changing the scrolling system is actually a great idea and you want to practice before Lion is released to the public, free app Scroll Reverser lets you do just that – on Snow Leopard (and 10.5, too). Once downloaded, it’ll sit in the menubar waiting for you to choose whether you want reversed scrolling or the normal one. A click on the dropdown menu allows you to make the change in seconds, and revert back again. The app can start at login, and has no additional preferences.
